Raspberry Pi Zero Pinout

As I have metioned earlier, Raspberry Pi Zero has 40 GPIO Pins. The following figure shows the Raspberry Pi Zero pinout:  

Raspberry Pi Zero Pin Description

Hope you’ve got a brief insight into the Raspberry Pi Zero. This section is dedicated to the description of pins incorporated into this tiny module.

Power and Ground Pins in RPi0

Raspberry Pi Zero Pinout has 3 voltage levels available, which are:

• 5V
• 3.3V
• 0V (Ground/GND)

So, if you are working on simple sensors i.e. humidity, PIR etc. then you can power them up using these power pins of Raspberry Pi Zero quite easily.

GPIO Pins in Raspberry Pi Zero

• GPIO pins are general-purpose input/output pins that can handle external devices.
• These pins are used to get/send commands/data to/from exrernal devices. (I hope you understood it :D )
• You can configure these pins to either general-purpose output or general-purpose input pins or as one of up to six special settings those functions are pin-dependent.

• External labels (from GPIO2 to GPIO27) represent the Broadcom (BCM) naming convention. This convention comes in handy when programming with Python libraries.
• Internal labels (from 1 to 40) represent the Board naming convention. This comes in handy when BCM is not supported. It is used with some programming libraries.

SPI Pins in Raspberry Pi Zero

The board contains one SPI communication protocol. SPI stands for a serial peripheral interface that supports master-slave communication. It is used to develop communication between the controller and other peripheral devices like sensors and shift registers. It comes with two Pins… MISO (master input slave output) and MOSI (master output slave input) for the SPI communication. Synchronization of data is carried out by using a clock (SCLK at GPIO11) from the master (RPi) and the information is delivered to the SPI component from the module using the MOSI pin. If the component requires to reply to our module, then it sends back data using the MISO pin.

I2C Pins in Raspberry Pi Zero

This module comes with one I2C communication protocol. It contains two pins SDL and SCL. The SDL is the serial data pin that carries the data while SCL is the serial clock line that ensures the synchronization of data transfer over the I2C bus. This communication protocol needs master-slave roles between the two parts.

UART Pins in Raspberry Pi Zero

There is one UART serial communication protocol incorporated on the board. The UART serial port comes with two pins Rx and Tx. The Rx is the receiving pin that ensures the receiving of serial data while Tx is the transmission pin that is used for the transmission of serial data.

How to Choose the Right Raspberry Pi

Choosing the right Raspberry Pi is like choosing the computer. In either case, you’ll list the requirements for accomplishing different tasks. More often than not, your requirements fall in the following list.

• Speed: The system’s processing power.
• I/O: How many I/O pins the module supports.
• Memory: How much memory RAM and ROM or HD space your system would require.
• Cost: The cost of the module.
• Size and weight: The weight and size of the module as per your requirement.

Speed is the key factor when it comes to choosing your computing system. More speed ensures more work is done in less time. The computers belong to this Pi series are more efficient and robust than microcontroller devices like PIC, Atmel, or Arduino boards.

• Similarly, memory is crucial when it comes to running large programs. Pick the RAM with more memory if you require large programs to run. The Raspberry Pi A computer comes with RAM that ranges between 256MB and 512MB of RAM. And the Pi 2 and 3B contain 1GB of RAM that is shared with the GPU. Make a final decision after analyzing the different functions you want to achieve with the Pi module.
• If you want to perform typical office tasks, like sending emails and writing a document, then a desktop PC or Laptop would be the best pick.
• Raspberry Pi modules are normally employed where there is a need for I/O. The Raspberry Pi A and B modules are suitable picks for attaching to external circuits and devices since they carry pin headers. The 1 A has 8 GPIO, while the +1 A and B computers have 17 GPIO.

Boost Converter using MOSFET IRFZ44N in Proteus

Hello Learner! Welcome to another exciting experiment at The Engineering Projects. We hope you are having a great day. In this lecture, we'll seek information about the Boost Converter Circuit from scratch to result in quick and easy steps. So, if you don't know about the experiment then don't worry because every Expert was once a Beginner. We'll talk about the following topics:

1. What is IRFZ44N MOSFET Boost Converter?
2. What is the brief introduction of components of circuit?
3. How can we implement the IRFZ44N MOSFET to design circuit of Boost Converter?

You will know some useful information about the topic in the DID YOU KNOW sections.

IRFZ44N MOSFET Boost Converter

During the experimentation of electronic circuits, we often face the situation when we have to amplify the voltage signals or voltage power. For example, when we need the 12V in the experiment but we have just 9V battery or any such case. There are many ways to tackle such condition but it requires a lot of energy and steps. But when we search our solution in the world of Switched Mode  DC-DC Converters, we find a very easy and simple solution of our problem in the form of IRFZ44N MOSFET Boost Converter. NOTE: One can make the BOOST Converter using one of many MOSFETs but we have focus on IRFZ44N due to its best result. Prior to start the experiment, it is compulsory to have some basic information about the circuit. We define the IRFZ44N MOSFET Boost Converter as:

The Boost Converter is the Electronic device that uses a MOSFET (IRFZ44N MOSFET in our case) to convert it's Low input DC Power into High output DC power.

The IRFZ44N MOSFET Boost Converter is a switched-mode power supply and this is consist of at least two semi-conductor device and minimum one energy storage element.

DID YOU KNOW????????????????

We call IRFZ44N MOSFET Boost Converter as Switched Mode Devices because basically, they are the semi-conductor Switches that turns their condition On and Off very rapidly.

Components of IRFZ44N MOSFET Boost Converter

Throughout the experiment, we'll use the components that will convert the low level Voltages into High Level Voltages. A brief introduction of the components is given next:

IRFZ44N MOSFET

The IRFZ44N Metal Oxide Semi-Conductor Field Effect Transistor is used as a switch in the IRFZ44N MOSFET Boost Converter. The main reason behind this is one can change its conductivity by changing its Gate Voltage and hence we can use it as a switch. This is one of the key procedure to amplify the voltages in the IRFZ44N MOSFET Boost Converter.

Inductor

We all know an inductor is a passive two- terminal magnetic storage device that stores the energy due to its coiled shape. Due to its storage capability, it resists the sudden change of current in the IRFZ44N MOSFET Boost Converter. In this way, it work as a stabilizer in the circuit and play an important role.

Diode

A diode is a reverse biased component of the IRFZ44N MOSFET Boost Converter. It is designed in such a way that it allow the flow of current only in one direction. Hence, in the IRFZ44N MOSFET Boost Converter the Diode allow the flow of current from inductor to the capacitor in only in the condition when it is forward biased.

Capacitor

A capacitor is a device that stores the energy in the form of charges. In IRFZ44N MOSFET Boost Converter when the Switch is turned off, the diode does not allow the flow of current through the capacitor. This is the condition when the stores energy in the form of charges from capacitor is used and the capacitor then works as the source of energy in IRFZ44N MOSFET Boost Converter.

Output graph

Before this we saw the components that we'll use in the formation of circuit, but we require other components as well to examine the result and working. We examine the result through an output device that shows us the result in the form of graph. For our experiment, we'll use analogue analysis graph for the output.

2SC2240 Datasheet, Pinout, Power Ratings, Equivalents & Applications

Hello Everyone! Happy to see you around. In this post today, we’ll cover the 2SC2240 NPN Transistor. We will have a look at the 2SC2240 Datasheet, Pinout, Power Ratings, Equivalents & Applications.

Electrons are the majority charge carriers in this NPN transistor, in contrast to PNP transistors, where holes are the majority carriers. The 2SC2240 comes with a power dissipation of 0.3W, the amount of energy this transistor dissipates while operating in the forward-biased state, while the collector current is 0.1A means it can support load up to 0.1A.

This NPN transistor contains 3 terminals, named:

1. Emitter
2. Collector
3. Base

If the voltage at the base terminal is above 0.7V, the transistor will get forward-biased and the current will start flowing from Collector to Emitter terminal. If the base voltage is less than 0.7V, it will remain reverse-biased.

So, let's have a look at the 2SC2240 NPN Transistor in detail. Let’s get started:

2SC2240 NPN Transistor

• The 2SC2240 is a bipolar junction transistor that belongs to the NPN transistor family.
• This component is mainly used for switching and amplification purposes and comes in a TO-92 package.
• 2SC2240 comes with three layers, with one p-doped layer between two n-doped layers.
• The two n-doped layers represent the Collector and Emitter, while the p-doped layer represents the Base Terminal.

• This device contains three terminals: the base, collector, and emitter. The collector terminal collects the electrons coming from the base side and the emitter terminal emits the electrons into the base terminal.
• The NPN transistors contain two junctions known as collector-base junction and emitter-base junction.
• The transistor is said to operate in a Forward-Biased state, when the collector-base junction is reverse-biased, while the emitter-base junction is forward-biased.
• When a negative voltage is applied at the emitter side and a positive voltage is available at the base terminal then we can make the emitter-base junction forward biased.

NPN vs. PNP: A Quick Recall

• Bipolar Junction Transistors(BJTs) are categorized into two types i.e. NPN transistors and PNP transistors. This is a bipolar transistor, which means both electrons and holes play a role in the conductivity process inside the transistor.
• But electrons are the major carriers in NPN transistors while in the case of PNP transistors, holes are the major carriers.
• NPN transistors are preferred over PNP transistors because the mobility of electrons is more efficient than the mobility of holes.
• These bipolar devices are called current-controlled devices, in opposition to MOSFETs, which are called voltage-controlled devices and carry terminals like a drain, source, and gate.

2SC2240 Datasheet

It’s wise to go through the 2SC2240 datasheet before you apply this device to your electrical project.

The following figure shows the 2SC2240 pinout.

This component contains three terminals named: 1: Emitter 2: Collector 3: Base

• These terminals differ in terms of size and doping concentration and are used for external connection with the electronic circuit. The emitter side is highly doped and the base side is lightly doped and the collector terminal is moderately doped.
• The collector terminal dissipates more energy compared to the other two terminals. It is bigger in size compared to base and emitter terminals. The large surface area of the collector side guarantees more heat dissipation.

2SC2240 Working Principle

The base is responsible for the transistor action. When voltage is applied at the base terminal, it will bias the device and as a result, the current will flow from collector to emitter terminal. As this is an NPN transistor so here current will flow from the collector to the emitter side and in the case of the PNP transistor current will flow from the emitter to the collector side. These bipolar devices are not symmetrical in nature. This projects if we exchange the emitter and collector pins then these terminals will start working in reverse active mode and will stop working in forward active mode. The different doping concentrations of these pins are the reason this device lack symmetry.

2SC2240 Power Ratings

The following table shows the 2SC2240 power ratings.

Absolute Maximum Ratings of 2SC2240
Pin No.	Pin Description	Pin Name
1	Collector-emitter voltage	120V
2	Collector-base voltage	120V
3	Base-emitter voltage	5V
4	Collector current	0.1A
5	Power dissipation	0.3W
6	Current gain	200 to 700
7	Operating and storage junction temperature range	-55 to 125C

• If these ratings are applied more than the required time, they can affect the device reliability.
• The collector-current is 0.1A which defines the amount of load this component can support.
• The power dissipation is 0.3W which represents the amount of energy released during the working of this component.
• The current gain ranges from 200 to 700 which is the amount of current this device can amplify.
• The operating and storage junction temperature ranges from -55 to 125C.
• The emitter-base voltage is 5V represents the voltage required to bias this component. The collector-base voltage and collector-emitter voltage both are 120V.
• When using this device, make sure these ratings don’t exceed the absolute maximum ratings else they can damage the device.

2SC2240 Equivalents

The following are the 2SC2240 equivalents.

• 2SC3201
• 2SC3245A
• 2SC3200
• 2SC3245
• 2SC2459
• KTC3200

Before applying alternatives into your projects, double-check the pinout of these equivalents as the pinout of 2SC2240 might differ from the pinout of the alternatives. The 2SA970 is a complementary PNP transistor to the 2SC2240.

2SC2240 Applications

The following are the 2SC2240 applications.

• Incorporated in modern electronic circuits.

Components of Embedded Systems

Hi Guys! I welcome you on board. In this post today, we’ll discuss the components of embedded systems.

An embedded system is a custom-built special purpose computer used for a specific purpose. It is a system that combines both hardware and software to perform a certain task.

It can be used as an individual system or a part of another large system. You will find embedded systems incorporated in a range of applications including consumer electronics, industrial machinery, automobiles, agriculture, processing industrial devices, airplanes, digital watches, vending machines, air-conditioners, mobile devices, and much more.

To understand the embedded system, we need to understand the difference between a special-purpose computer and a general-purpose computer. General-purpose computers are those that we use every day like our desktops, laptops, and Macs. Even our smartphones stand in the general-purpose end of the spectrum which means they have more than one specific task to perform. Special purpose computers are very specific to serve a particular function. A calculator is a special-purpose computer as compared to a laptop that is a general-purpose computer. The only job of a calculator is to do calculations. You cannot use it for more than one purpose like general-purpose computers.

An automated system that doesn’t involve human interference is also an example of an embedded system. For example, you can interface the conveyer belt with the sensor to count the number of filled bottles. Once you install a combination of both hardware and software embedded programming, you can watch the number of filled bottles on the computer screen without any human interference. The devices that perform certain tasks where no user is involved are termed as the no user interface (UI) embedded systems and where user interference is involved are termed as graphical user interface (GUI) embedded systems.

Read this post all the way through as we’ll discuss the basic components of embedded systems in detail.

Let’s get started.

Components of Embedded Systems

This section is dedicated to the hardware components of embedded systems. In the following section, we’ll cover the software components used for the embedded systems.

1. Power Supply

• A power supply is a crucial component of the embedded system design.
• It is an electrical device mainly used to power up the electrical load.
• Normally, a 5V power supply is required for the system, however, it can also range from 1.8 to 3.3V.
• You can pick either one based on your requirements and application.

To work the embedded system properly, a smooth and efficient power supply is needed. Both wall adopter and battery can be used as a power supply. Some power supplies work as independent equipment while others are incorporated into the embedded technology they power.

2. Microcontroller

• An embedded system is either a microcontroller-based or microprocessor-based system. They give a system computing power and are called integrated circuits.
• The embedded hardware performance is mainly dependent on the processor which is normally called the brain of the embedded system.
• Pick from a range of processors including 8-bit, 16-bit, and 32-bit processors.
• They are different in terms of processing speed. For example, a 32-bit processor comes with more processing speed and can manipulate 32-bits at a time while an 8-bit processor comes with less processing speed and can manipulate 8-bits at a time.

For simple applications, an 8-bit processor would suffice while for complex and advanced applications, processors with more bits are used. The 8-bit processor is normally clocked to 8MHz while the 32-bit processor can run up to hundreds of MHz.

3. ROM/RAM

• Memory is essential to store important information in the embedded computer system.
• Memory is integrated into a microcontroller or microprocessor.

There are two types of memories including ROM (read-only-memory) and RAM (random access memory). The former is called the code memory that stores the program code and is non-volatile which means it stays stored in the system when the power supply is removed. While latter is called the data memory and is a volatile memory which means it is used for temporally storing the information and is removed from the system when the power supply is turned off.

4. Timers / Counters

Sometimes you need to create a delay before a specific function. Timers are used in such cases. While at times you want to count the number of times a particular event occurs. Counters are used in such cases. If an up counter is used in the system, it will count up from the initial value to 0xFF and if it is down counter, it will count down to 0x00.  The counters are integrated using register-type circuits like a flip-flop.

5. Communication Ports

Communication ports are used in embedded systems to establish communication with other embedded systems. There are several communication ports including USB, UART, USB, I2C, SPI, and RS-485. For simple applications, communications ports are utilized from the microcontroller, and for complex and advanced applications these ports are externally installed inside the embedded systems.

6. Output and Input

Input is required to interact with the embedded system. A sensor can be used to provide input to the system. The microcontroller used in the system can be configured as an input or output port. In the microcontroller, there are a fixed number of input and output ports that you can utilize as per your requirement.

7. Electrical Circuit

You need to design an electrical circuit based on your application. The following are the basic circuit components that can be used in an electrical circuit.

a. PCB (printed circuit board)

A PCB is an essential part of the electrical circuit. It is a mechanical circuit board that electrically connects the electronic components with conductive copper traces. Before making the electrical design on the PCB, you need to design the electrical circuit on the PCB simulation software to test if the required design will work in reality. Making electronic circuits with PCB is cheaper and more efficient than point-to-point and wire wrap construction.

b. Resistors

A resistor is an electrical component mainly used to produce resistance in the current flow. It is mainly employed to reduce the flow of current, for adjusting the signal levels. In power distribution systems and motor controls, resistors with high power are used that can dissipate more heat in the form of energy. Resistors are further divided into two types i.e fixed resistors and variable resistors.

The resistance of fixed resistors changes with temperature and variable resistors can be utilized as sensing devices for humidity, light, force, and heat. The resistor’s electrical function is dependent on its resistance. The more the resistance, the more it will create resistance in the current flow.

c. Capacitors

A capacitor is a two-terminal electrical device mainly employed to store energy. The capacitance of the capacitor is commonly known as the effect of a capacitor. Capacitors are available in various forms though, most capacitors come with two electrical conductors which are separated by a dielectric material. Capacitors are widely used in many applications for various purposes including smoothing, bypassing, and filtering the electrical signal. Capacitors store energy and release it when it is required by the circuit.

d. Transistors

Transistors are used in the electrical circuit for amplification and switching purposes. They are divided into two main types i.e. bipolar junction transistors and MOSFETs (metal-oxide-semiconductor field-effect transistors). The former is the current-controlled device and comes with terminals like base, collector, and emitter.

The latter is the voltage-controlled devices and comes with terminals like a drain, source, and gate. They are used in a range of applications including computers, stoves, pacemakers, aircraft, motor control, and much more. Their working principle is simple and straightforward. The small current at one terminal is used to produce a large current at the remaining terminals. This phenomenon is used for amplification purposes.

e. Diodes

A diode is an electrical component that uses PN-junction and allows the current to flow in one direction only. Mostly didoes are made of semiconductor material like silicon but some diodes are also composed of germanium. Diodes are used in a range of applications including signal mixers, switches, voltage regulators, logic gates, clippers, limiters, clampers, and gain control circuits.

f. Integrated Circuits

An integrated circuit is a chip that combines various electrical components into a single chip. An IC is a ready-made chip that you incorporate into your electrical project without having to include lots of capacitors and resistors. A small integrated chip can work as an oscillator, amplifier, microprocessor, timer, and computer memory. If you open the CPU of your computer, you will find scores of ICs integrated into the motherboard of the computer. A single IC can hold hundreds of thousands of resistors, transistors, and capacitors inside.

g. LED

LED (light-emitting diode) is widely used in electronic circuits. LEDs are included in circuits for some indication to check if the circuit is working properly. This electrical component is so reliable and can last decades without decaying. Using LEDs you can identify the state of current in an electrical circuit. For example, you can integrate LED into your circuit where the blinking of LED will indicate the circuit is working properly.

h. Inductors

An inductor is an electrical component used to store energy in an electric field in the presence of an electrical current. The inductors come with an insulated wire that circles the coil. These electrical components work on Faraday’s law of induction where the electric motive force is induced in the conductor by varying magnetic fields in the presence of current passing through the coil. Inductors are employed to block AC while permitting the DC to flow. Inductors utilized for this purpose are named… chokes.

Embedded System Software Components

Recall, an embedded system is a combination of both hardware and software modules. We have briefly explained above the hardware embedded system components. This portion is dedicated to software components of embedded systems. Both computer software and embedded system software are different in terms of their purposes. The computer software can be installed on many devices to achieve the required goals while embedded system software, on the other hand, is specifically written for a certain device to meet a certain goal.

The following are the software components of embedded system.

a. Editor

• The editor is the first tool you required for embedded system software.
• The code you write in C and C++ programming languages will be saved in a text file in the editor.

• Geany editor is a great example of a text editor.
• This editor supports scores of languages including Java, C, HTML, Python, PHP, Pascal, and Pearl.

b. Compiler

• The code is written in a text editor. But how does a machine understand this code?
• A compiler is used to turn this written code into low-level machine language that the machine can comprehend.
• The main purpose of this tool is to develop an executable program.

• The name ‘compiler’ is mainly used for the written programs that convert high-level programming language source code into a low-level programming language.

c. Assembler

• The assembler tool converts the written code into a machine language. It is slightly different than a compiler.
• The compiler directly converts the written code into machine language while the assembler, on the other hand, first converts source code to object code and then to the language that the machine can understand.

d. Emulator

• The main task of the emulator is to make the embedded system act like a real system in a simulation environment.
• Using an emulator, you’ll get an idea of how the code will function in real-time. It is used to simulate software performance, and it helps in achieving the ideal performance of the written code.
• With an emulator, you can run one operating system into another device. For example, using an emulator you can run Mac operating system into your windows operating system.

e. Linker

• Typically, software code is written in small modules and pieces.
• A linker, also called a link editor, is a tool that takes one or more object files and combines them to develop a single executable code.

f. Debugger

• A debugger is a tool used for testing and debugging purposes. It scans the code thoroughly and removes the errors and bugs, and identifies the places where they occur.
• Programmers can quickly address the errors and fix them.

What is Mechatronics Engineering? Courses, Jobs, Salary, Scope & Projects

Hello friends, I hope you all are doing great. In today's tutorial, I will give you a detailed information about What is Mechatronics Engineering? We will also cover Mechatronics Courses, Jobs, Salary, Scope & Projects. If you ask me, Mechatronics is the most advanced & stylish one of all the Engineering Branches. Even if you look at its name, it's so different & macho-type, other engineering branches' names are so typical i.e. Electrical, Electronics etc. (No offence :P) I may sound a little biased because I am also a Mechatronics Engineer. B| Anyways, let's start with the question: What is Mechatronics Engineering?

What is Mechatronics Engineering?

Mechatronics Engineering is not a pure engineering branch, instead a merger of various engineering fields, major ingredients are mechanical, electronics, control & computer engineering and is used to design smart & intelligent machines. It's name is also taken from first two major fields i.e. "Mecha" from Mechanical & "tronics" from Electronics. Apart from these two main engineering fields, it also has the flavour of computer, telecommunication, robotics, control, systems engineering etc. Mechatronics has a wide range of advanced fields & few of them are: Robotics, Automation, Embedded Systems, Control Systems, Artificial Intelligence, Machine Learning etc.

Why Mechatronics Degree Created?

Before Mechatronics Degree, machines were quite simple and weren't smart enough to work on their own so human operators were required to operate them, which resulted in human error, cost-inefficiency, time wastage etc. With the evolution of technology, engineers got to know about Machine Learning & they started designing smart systems for controlling mechanical machines/structures with electronics(embedded to be precise) circuitry i.e. Electric Locomotive. Let's understand it with an example. You must have seen robots in sci-fi tv shows, they have a mechanical structure and electronics circuitry embedded inside it. So, if you want to design robots, you need to hire two different engineers i.e. mechanical engineer for structure/body designing & electronics engineer for designing the circuitry. So, in order to fill this gap & to make the process cost-efficient, Mechatronics Degree was introduced. Degree of Mechatronics has further evolved with the addition of computer-aided design software. Another example is of a car rear-view mirror. Initially, it was a simple mirror. Now it has cameras, compass direction, register temperature, sensory systems etc. Mechatronics is behind these revolutionary changes. Mechatronics devices are also used in medicine, home, commercial buildings, agriculture, toys, etc.

History of Mechatronics

The term mechatronics originated in Japan in the 1960s and the term was first coined by Tetsuro Mori, a Japanese engineer. The field is said to have grown from robotics. Initially, when robots were designed, the arms were uncoordinated and had no sensory feedback. However, as science advanced and developments were made in sensory technology, controls, and programming, the arms and overall robotic movements became coordinated & controllable. When mechatronics was initially developed, it was only viewed as electromechanical systems and this is where its name originates from. It's name was coined by Yaskawa; the company that is famous for combining words and concepts like this. Yaskawa had registered the name mechatronics and won its rights in the early 70s. However, in the 1980s, Yaskawa released the rights so that they could be used publicly. After this event, the term started gaining popularity. When it was newly developed, its main focus was servo technology which converts electricity into precisely controlled motion. With the help of this, it created automatic door openers and auto-focus cameras. After a decade in the 1980s, mechatronics diverted its focus to information technology. It improved the performance of antilock braking and electric seats by attaching microprocessors into mechanical systems. Eventually, in the 1990s, mechatronics focused on communication technology and connected products into large networks. The application area of mechatronics engineering has substantially broadened. The technology is now used in the automation of machines, industrial goods, biomedical systems, servo mechanisms, computer-aided designs, data communication systems, CNC and DNC systems etc.

Mechatronics Degree Colleges & Universities

Mechatronics Degree has emerged rapidly in the last few decades. Initially, it was referred as the sub-branch of mechanical engineering but later because of its growing industrial needs, it has finally become a separate branch of engineering itself. Today, Mechatronics degrees are offered by almost every top Engineering College & University. Below Table shows few Mechatronics Degree Colleges & Universities:

Mechatronics Degree Colleges & Universities
No.	College/University	Location
1	Arizona State University	Phoenix, USA
2	Centennial College	Toronto, Canada
3	Cranfield University	Bedford, UK
4	Institute of Technology Sligo	Sligo, Ireland
5	Kwantlen Polytechnic University	Surrey, Canada
6	Liverpool Hope University	Liverpool, UK
7	London Metropolitan University	London, UK
8	Maynooth University	Maynooth, Ireland
9	Millersville University	Millersville, USA
10	Mohawk Valley Community College	Utica, USA

Mechatronics Courses

You must have heard the proverb: "Jack of all trades, master of none". That applies to a Mechatronics engineer but in its fullest form. “A jack of all trades is a master of none, but oftentimes better than a master of one.” Mechatronics has a wide range of courses, few of them are actually designed for Mechatronics while most of them are borrowed from other engineering fields. If you have a look at the Mechatronics subjects list for Bachelor's Degree, you won't find a symmetry. In Electrical Engineering, students are studying electrical subjects mostly but in Mechatronics Engineering, you are studying Mechanical, Electronics & programming in the same semester. (that's why I used that proverb at that start) Here's a list Mechatronics Courses:

Mechatronics Courses
1	Embedded Systems
2	Hydraulics & Pneumatics
3	Control Systems
4	Machine Learning
5	Signal & Systems
6	Telecommunication
7	Numerical Methods
8	Robotics
9	Artificial Intelligence
10	Data Processing

Mechatronics Projects

In the last year of Mechatronics Bachelor's Degree, students have to design & present a Final Year Project, which has to be related to any subdomain of Mechatronics. Here's a list of few Mechatronics Projects to get an idea:

Mechatronics Projects
1	Home Automation System
2	Bank Security System
3	Self Balancing Robot
4	Path Finding Robot
5	Smart Bottle Filling System
6	IOT Mesh Networking
7	Image Processing based Waiter Robot
8	Obstacle Avoidance Robot
9	Wifi based Surveillance System
10	Smart Irrigation System

Mechatronics Jobs Sector

As mechatronics involves subjects related to multiple fields i.e. electrical, mechanical, computer engineering etc. so its applications & thus jobs have no limits. Fresh Mechatronics graduates can easily find a decent job and here's a piece of advice, just make sure you build your career in the pure mechatronics industry, instead of electrical or mechanical. Mechatronics is a demanding career with expanding job ranges. Businesses/Industries are updating their technologies and turning to intelligent systems and robotics. Let's discuss few of Mechatronics scopes:

Mechatronics Jobs in Agriculture

Agriculture, being one of the oldest industries, initially relied solely on human and animal efforts. When the industrial revolution began, it made agriculture relatively easier. Diesel and steam engine tractors were used as well as hydrostatic power equipment. Mechatronics has now arrived and it is making things way too easier with its advanced technologies i.e. microcontrollers, actuators, sensors etc. Mechatronics is now playing a significant role in cropping, cleaning, fertilizing, seeding, monitoring etc. Crop colours, alcohol levels, moisture levels, chemical levels, insecticides levels, pesticides levels, light levels etc. are now being detected with the help of different embedded sensors. A mechatronics engineer can join the agriculture field as an embedded expert. If we talk about salary, a degree in mechatronics may earn $52,000 per annum.

Mechatronics Jobs in Food industry

Mechatronics is being greatly used in the food industry from cooking to packaging to manufacturing. Lean manufacturing is in demand in the food industries and for this reason, mechatronics has found its way into it.

Mechatronics Jobs in Renewable Energy

As global warming is increasing and measures are being taken to control the environmental hazards, renewable energy is being given importance and preference that in turn is creating more job opportunities. A bachelor’s degree in mechatronics provides an engineer with various jobs in wind energy, hydropower, solar power, geothermal technologies, etc. Mechatronics engineers will find various opportunities in this field and can bring innovations using their skills. Mechatronics engineers are responsible for testing and improving components used in solar panels, wind turbines, and other modules used for generating renewable energy. A mechatronics engineer may join this industry as an energy systems technician, safety coordinator, materials engineer, and many other positions. If we talk about salary, the salary for mechatronics engineers in this field is relatively higher. Mechatronics engineers in wind power earn an average salary of $84,000 per annum. While in solar power he earns $87,000 per annum on average. The wind turbine installer earns around $100,000 with experience.

Mechatronics Jobs in Homeland Security and Defense:

It has been predicted that 40% of military ground troops will be robots in near future. This prediction, if came true, will increase the mechatronics applications in the military and robotic sector. Mechatronics engineers can also find their scope in drone technologies, border control, logistics, surveillance, ground operations, etc.

Mechatronics Jobs in Medical Industry

Although mechatronics is being used in numerous industries, it has been way too successful in the medical field. The utilization of mechatronics techniques allows for miniaturization. Using the technique, a patient can be examined, sensed, and monitored from inside. This technique has revolutionized the field of healthcare and has a profound effect. Devices are used that allow sensors to detect chemical, biological as well as physical signals. This technique helps in the early detection of a patient’s medical issues. The mechatronics also designs and creates tools for endoscopic surgery, robotic surgical devices, home monitoring, telemedicine, implanted devices, etc. Using mechatronics techniques, many profound medical things have been created so far. For example, defibrillators, arthroscopic devices, ultrasonic probes, cardiac pacemakers, etc. Below are examples of some revolutionary mechatronics techniques that are being used in the healthcare industry:

Mechatronics Jobs in Prosthetic limbs

The prosthetic hand is created with microprocessors that enable precise manipulation. It handles a variety of movements. For example, threading a needle or picking up an egg. It has been designed to use a combination of actuators, microprocessors, sensors, and control software. When these combinations are used, we see a prosthetic hand that mimics a real hand. It has been approved by the US Food and Drug Administration. The FDA considers it the device that is capable of making multiple movements with the help of muscle contractions detected by electromyogram electrodes. The prosthetic hand is built with computers and motion sensors that enable it to make movements. Surgical system The Da Vinci Surgical System is another great innovation by mechatronics. It is a robotic surgical system and was developed by Intuitive Surgical. It is a robotic-assisted surgery platform. After a surgical cut is made on the patient, the actions of the robotic arms are manipulated by the surgeon that in turn enables the robotic arm to sync with the surgeon’s movements.

Mechatronics Applications

Although Mechatronics has a wide range of applications. I've mentioned few of Mechatronics Applications below:

• Medical mechatronics, medical imaging systems.
• Computer-aided and integrated manufacturing systems.
• Machine vision
• Automation.
• Robotics.
• Security.
• Computer-driven machines i.e. CNC milling machines, CNC water jets, CNC plasma cutters etc.
• Structural dynamic systems.
• Modern Transportation systems.
• Sensing and control systems.
• Engineering & Manufacturing systems.
• Packaging.
• Microcontrollers / PLCs.

So, that was all about Mechatronics Engineering. Thanks for reading. Have a good day !!!

Modern Technology Improves Efficiency Of Construction Vehicles

Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How Modern Technology Improves the Efficiency Of Construction Vehicles. The building industry has been slow to embrace technology, and still, only one in eight construction executives consider their company to be technologically advanced. However, where greater digitization has been adopted, it has been shown to increase productivity and enable better collaboration.

It’s easy to see how certain aspects of construction such as designing plans, manipulating 3D models and sourcing materials can be enhanced by technology. In contrast, heavy machinery and manual labor are still essential on-site to carry out the hard, physical work of construction. However, with the introduction of telematics and AI, and a switch to more electric vehicles and automated machinery, even heavy vehicles can be made safer and more efficient with technology.

Digital Vehicle Maintenance Programs

Of all construction projects undertaken, only 30% are completed on time, with delays often attributed to faulty or broken down machinery. To avoid unnecessary downtime and improve productivity, high-tech maintenance programs can streamline the upkeep and repair of heavy equipment. When telematics, sensors and instrumentation are installed on on-site equipment, large amounts of data can be analyzed to see how vehicles are performing.

Information gathered from sensors can help to identify when machinery is active or idle, allowing contractors to improve productivity and maximize fuel efficiency. This data can also be used to predict future problems and promptly deal with maintenance and repair issues before they cause unnecessary delays. Some parts need changing regularly to ensure the smooth running of equipment. With scheduling software, it’s easy to check when to replace the air filters on a crawler bulldozer or keep a record of upgrading Bobcat 3T320 tracks to match the performance of the new powerful compact loader. Implementing regular upgrades and repairs saves time in the long run, and helps to prevent building projects from exceeding projected budgets and schedules.

Autonomous And Remote Controlled Vehicles

Maintaining vehicles and heavy equipment is essential, not only to increase productivity but also to improve safety levels for on-site operators. The most common cause of injury for construction workers on site is being struck by vehicles, machinery or other building materials, and around 75% of the fatalities from being struck involve heavy vehicles such as trucks or cranes. As the use of self-driving construction equipment is becoming more common, these accidents and injuries could be minimized. Machines equipped with sensors, cameras and Light Detection and Ranging Laser Scanning technology (LIDAR) can easily detect workers and other machinery to avoid collisions. With remote control technology, workers can safely operate machines using a transmitter or even a smartphone app. Away from the cab, they are safe from the dangers of machinery toppling over on them, and, with unobstructed views of the site, they can take away the risk of other workers being pinned or crushed by vehicles.

Wireless Communication Enables Autonomous Mining

Autonomous machinery is already used widely in the mining industry. Sensors and cameras provide data to enable machine learning AI to drive a variety of vehicles, and some mines have now replaced manually driven equipment with fully autonomous diggers and crushers. Fully automated mines are possible where reliable wireless communication is available, allowing for fast and dependable mobile connections. This means that trucks and other vehicles can be controlled from a distance by a single operator, improving productivity and reducing costly communication errors.

Electric Construction Vehicles Reduce Carbon Emissions

On-site construction processes, including the use of heavy machinery, account for 11% of all global carbon emissions. In the US, The Environmental Protection Agency (EPA) has been introducing increasingly stricter limitations on emissions for off-road diesel engines, and in the future, it is likely that requirements for zero emissions from heavy construction vehicles could be introduced. This means the introduction of more electric vehicles, which, as well as being cleaner, are cheaper to run and less noisy. This is a particular benefit for sites in congested cities where pollution from noise and emissions is more strictly regulated.

Although the construction industry has been slow to digitize, new technologies are helping to streamline processes and improve productivity. This now also applies to vehicles and heavy machinery that are being adapted to run more efficiently, produce fewer emissions, and reduce the risk of accidents on site.

How Can Financial Knowledge Help Your Engineering Career Succeed?

Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you How Can Financial Knowledge Help Your Engineering Career Succeed? A solid foundation in financial knowledge is the most sought after trait not only in finance jobs but also in many other fields. Perhaps, it's because finance is a common denominator that impacts all industries. Not only does it communicate the overall health of an organization, but it also affects every person in a certain workplace. Whether it's public, corporate, or personal finance, understanding it can benefit you in many different ways. But for one thing, it can help jumpstart or advance your career in engineering. In fact, finance and engineering make up a powerful combination, especially in asset-intensive industries. Nevertheless, how does your knowledge in finance help your engineering career succeed? Keep on reading and learn how to take your career path to the next level.

Understand The Financial Aspect of Every Project

Engineering is largely based on building, designing, and creating projects. With that, one of the critical components of doing the job is determining what type of materials you should use and why. If you don't have a finance background, it can be challenging to calculate the operating and maintenance costs of every project. As an aftermath, the cost of a particular project may spiral out of control, which can significantly affect the overall budget of the organization you're working for. But knowledge of finance can help you execute more cost-effective projects. That's precisely why having a financial understanding is an essential reinforcement of your engineering skills.

Overcome Multiple Work-Related Problems

Similar to engineering, finance also utilizes higher-order thinking skills. But the advantage of studying finance after engineering is you can develop more skills in problem-solving. As a result, it's easier for you to identify potential problems and come up with workable solutions. Remember that an engineer's daily activities typically center on solving complex problems. When working on intricate matters, anyone can easily get lost in the details, failing to see the bigger picture. The good news was when you developed both engineering and financial skills, you'd be more capable of thinking outside the box. Thus, an engineer with a design vision is important to make every project successful no matter what the problem is.

Gives You An Edge For Leadership Roles

As you climb up the corporate ladder, you'll be more exposed to managing money and resources. Devising a plan on spending and justifying reasoning is part of the day-to-day activities of engineers. But since finance is also all about the wise allocation and spending of essential resources, it's definitely an excellent addition to your expertise as an engineer. Note that a company's CEO has to ensure that every money invested in a specific project won't go to waste. Your engineering skills most likely have taught you to use high-end material that is expensive. But you need financial knowledge to prove to the management that such an outlay is necessary. Having these two can give you an edge for leadership roles.

Leverage For A Raise Or Promotion

Once you develop your financial knowledge and skills, you can better understand how your work specifically contributes to your company's financial health. You can then leverage such information to elevate your earning potential. Although engineering jobs are known to have a high compensation, engineers feel the pinch when it comes to salary and benefits. Based on a salary and career survey, many of them complained about the compensation policies due to overloaded work. If you want to break that statistic, you have to know the value of your work in the company. It may not be an easy negotiation, but you can better prove your points when you have strong finance knowledge. However, make sure to research the standard pay range of your education, skills, and experience level before doing this.

Navigates Great Investment Opportunities

Engineering helps improve how the world operates, whether it's through commercial products or public engineering. But then again, analyzing the economic effects of these engineering projects is of great importance. Every project comes with a cost, and finance can empower you to push back against projects with little chance of success. With financial knowledge, you can take every engineering effort in a more promising direction, which may lead to great investment opportunities. Besides that, you'll have more advantages over a competing project in another industry.

Provides An Avenue For Employment Opportunities

Having both degrees in engineering and finance provide an avenue for more employment opportunities. Many industries nowadays prefer to employ people with more knowledge in a range of skills. But since engineering and finance are greatly beneficial in any industry, it will be much easier for you to find opportunities to advance your career path.

Final Thoughts

Like in other fields, it might be hard to find your place as an engineer in a competitive job market. But enhancing your business and financial knowledge can help you make a great impact on the company you work for and take your engineering career to the next level. It's like hitting two birds in one stone. You contribute to the company and boost your career at the same time.

KSC1845 Datasheet, Pinout, Power Ratings, Equivalents & Applications

Hi Guys! I welcome you on board. In this post today, we’ll discuss the KSC1845 NPN Transistor. We will have a look at the KSC1845 Datasheet, Pinout, Power Ratings, Equivalents & Applications in detail. As it's an NPN transistor, electrons are the majority charge carriers and thus play a major role in conductivity. KSC1845 is mainly used for fast-switching and amplification purposes.

NPN transistor carries 3 terminals, known as:

• Emitter
• Collector
• Base

If the applied voltage at the base terminal exceeds 0.7V, it will forward bias this NPN transistor and the current will start to flow from Collector to Emitter. If the base voltage is less than 0.7V, KSC1845 will remain in the reverse-biased state.

I suggest you buckle up as I’ll discuss the KSC1845 NPN Transistor in detail. Let’s get started:

KSC1845 NPN Transistor

• The KSC1845 is a bipolar junction transistor that falls under the NPN transistor family.
• It is made of silicon semiconductor material and comes in a TO-92 package.
• The NPN transistors carry two junctions known as emitter-base junction and collector-base junction.
• When the emitter-base junction is forward-biased and the collector-base junction is reverse-biased, the transistor starts to conduct.
• KSC1845 Pinout, Symbol and SMD Package are shown in the below figure:
  

• We can make the emitter-base junction forward-biased, by applying a negative voltage at its Emitter and a positive voltage at its Base.
• KSC1845 contains three layers where one p-doped layer sits between two n-doped layers. The p-doped layer represents the base terminal while the other two n-doped layers represent Collector and Emitter.
• In a forward-biased state, the Emitter emits the electron into the Base while the Collector collects the electrons coming from the Base.

NPN vs PNP

KSC1845 is a Bipolar Junction Transistor, so let's quickly recall it:

• The bipolar junction transistors come in two types i.e. NPN transistors and PNP transistors. Both holes and electrons play a role in carrying out the conductivity process inside the transistor.
• In PNP transistors, holes are the majority charge carriers, while in NPN transistors, electrons are the majority charge carriers.
• Know that the mobility of electrons is better than the mobility of holes, that's why NPN transistors are preferred over PNP transistors for a range of applications.
• These bipolar(BJT) components are called current-controlled devices in opposition to MOSFETs, which are considered voltage-controlled devices and carry terminals like a drain, source, and gate.

KSC1845 Datasheet

Before you incorporate this device into your electrical project, it’s wise to go through the KSC1845 datasheet that details the main characteristics of the device. Click the link below to download the KSC1845 datasheet.

KSC1845 Pinout

The following figure shows the KSC1845 pinout.

This component contains three terminals named: 1: Emitter 2: Collector 3: Base All these terminals are used for the external connection with the electronic circuit. These terminals differ in terms of size and doping concentration. The base side is lightly doped and the emitter side is highly doped while the collector side is moderately doped. The collector side dissipates more energy because it is bigger in size compared to other terminals. The large surface area of the collector side ensures more heat dissipation.

KSC1845 Working Principle

The base side is the main region that initiates the transistor action. When voltage is applied at the base terminal, it will bias the device and as a result, current starts flowing from collector to emitter side. These bipolar devices are not symmetrical in nature. Which means if we exchange the emitter and collector sides then these terminals will stop working in forward active region and start working in reverse active mode. The different doping concentrations of these terminals ensure the lack of symmetry.

KSC1845 Power Ratings

The following table represents the KSC1845 power ratings.

Absolute Maximum Ratings of KSC1845
Pin No.	Pin Description	Pin Name
1	Collector-emitter voltage	120V
2	Collector-base voltage	120V
3	Base-emitter voltage	5V
4	Collector current	0.05A
5	Power dissipation	0.5W
6	Current gain	200
7	Operating and storage junction temperature range	-55 to 150C

• When using this device, make sure these ratings don’t exceed the absolute maximum ratings else they can damage the device.
• Plus, if these ratings are applied more than the required time, they can affect the device reliability.

• The collector-current is 0.05A which shows the amount of load this device can support.
• The power dissipation is 0.5W which represents the amount of energy released during the working of this component.
• The current gain is 200 which shows the amount of current this device can amplify.
• The collector-base voltage is 120V and the collector-emitter voltage is 120V. The emitter-base voltage is 5V represents the voltage required to bias this component.
