Web Design vs. Web Development

Hi Friends! Welcome to The Engineering Projects. At the present time, it is an important to upgrade the technical skills. As we approach a more digital era, the use of the internet has become part of our day-to-day activities. When it comes to looking up for something online, we always go to our chosen and trusted websites for information. Our trusted website, of course, is pleasing to the eyes, with all the functions and settings working perfectly. Although as a browser, we would sometimes not bother to give a second look at the web design or how it was developed. But if by any chance, your mind seeks to know more, to have in-depth knowledge about websites in general, this article seeks to explain the difference between web design and web development.

Web Design and Web Development: Which Is Which?

Web Design

In layman’s terms, web design involves the aesthetic of a particular website. It is how the site looks from an outsider’s point of view. The web designer’s job includes making the website look aesthetically-pleasing to its viewers—these would include a selection of the color scheme to be used, selection of the font and font size, and where the website functions should be placed.  Web design mainly requires the artistic and creative touch of the web designer. Aside from the aesthetic look of a website, there are numerous areas in web design that the web designer should never neglect, including the user interface design (UI), the graphic design, user experience design (UX), and search engine optimization (SEO). To make web design possible, web designers use a bunch of tools that would be perfect for the production process that they would be needing. Web designers normally would use vector and raster graphics editor in order to make design prototypes or web-formatted images. The tools that they use are updated from time to time in order to always have an updated software or standards. Web designers also use technologies to create websites like CSS and HTML. The UI and UX of a website are also considered in the web design. The UX pertains to the layout, including labeling and clear instructions on each function. UI, however, is the more commonly used function of a website, as this pertains to the website’s interface as a whole.

Web Development

As the back end (and front end) of a website, web application development services consist of all the software and programs that are needed in making the website thoroughly and smoothly functioning. A web developer’s main objective is to develop the backend of a website to give a pleasing and smooth web experience for whoever will browse the website. Since web development is a complicated and tedious task, it requires a skilled and skilled web developer, who is also familiar with technical computer languages such as Java, ASP, Coldfusion, and PHP, among others. Web development can be as simple as making a single static page or even making web-based applications of the internet and web apps. Web developers have numerous tasks to accomplish when developing a website. These include web engineering, web content development, client-side or server-side scripting, web server, network security configuration, e-commerce development, and even web design. Web development sometimes uses content management systems (CMS) in order to make the necessary changes in the content easier and more accessible with basic technical skills.  Web Design vs. Web Development: Brief Summary Both web development and web design are important in making a website. These two approaches (front end and back end) when combined, produce, and develop the system and design needed for a completely working and aesthetically-pleasing website. Web development mostly pertains to the back end of a website, making sure that all the systems, functions, and configuration are working properly. This may be unseen by the web browser but can surely experience it upon browsing any given website. The website’s aesthetic look and design, however, is part of the work of a web designer. As a skilled web designer, the graphics, colors, fonts, graphics placement, UI and UX, and features placement are included in the whole web design. Web design and web development work hand-in-hand. You cannot develop a website with just a web design, just as you cannot make your design work with just the web design.

Master Slave JK Flip Flops in Proteus ISIS

Hey pals! I wish you are doing great. Welcome to a new lesson about the Digital Logic Circuits in The Engineering Projects. In the past tutorials, we Designed the Basic JK Flip Flop. Today, we'll talk about the following Points:

1. What are JK Flip Flops?
2. What are the Master Slave Flip Flops?
3. How does the Circuit of Master Slave Flip Flop looks?
4. How types of JK Flip Flop different from each other?
5. How does the simulation of Master JK Flip Flip take place in Proteus ISIS?

Moreover, we'll also learn some key concepts in DID YOU KNOW portions. Yet Let's recall some points about the topic.  Flip Flops are the building block of a huge number of electronic systems and devices. A Flip Flop is a Digital circuit that can take the bits as input, work with the bits, Store the bits and can output the bits. it has four basic types and at the moment we are discussing the JK Flip Flops.

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

The basic JK Flip Flops face a condition where when both the Inputs are HIGH and the Clock remains HIGH for a long time, then the output of JK Flip Flop becomes uncertain and this situation is called Race around Condition in JK Flip Flops..

JK Flip Flops

As discussed in the Previous tutorial , we define the JK Flip Flops as:

"The JK Flip Flops are the Modification of Set-Reset Flip Flops that contain two outputs and are able to work with the Invalid Condition of Flip Flops."

There are mainly two types of JK Flip Flops:

1. Basic JK Flip Flops
2. Master Slave JK Flip Flops.

The main focus of this tutorial is Master JK Flip Flops so lets find what are they.

Master Slave JK Flip Flops

The Master Slave JK Flip Flops are considered better than Basic JK Flop and we define them as:

"Master Slave JK Flip Flop is two input two output sequential Logic Circuits that are the Combination of two Basic JK Flip Flops and  work well even in Race around Condition of JK Flip Flops."

In Master Slave JK Flip Flops there are two JK Flip Flops that are connected in series. The 1st JK Flip flop is called the "Master" circuit and the other is called the "Slave" circuit. The output of the Master Circuit is connected with the inputs of Slave circuits. At the same token, the output from the Slave Circuit are then fed into the input terminals of Master Circuit. The circuit also contain an Invertor that is Connected with the clock and slave circuit in such a way that the Slave circuit always contain the inverting clock signal as the master circuit. Hence when Master circuit get the clock HIGH, then the slave circuit get the LOW and vise Versa.

Difference of Basic JK Flip Flop and Master Slave JK Flip Flop

Both of the circuits belongs to the same family but they are different in many ways:

1. Basic JK Flip Flop contain only one circuit but Master Slave JK Flip Flop contains two.
2. The Basic JK Flip Flop have the Race around condition but Master Slave does not.
3. Basic JK Flip Flop is less complex than Master Slave JK Flip Flop.
4. Basic JK Flip Flop is less used than Master Slave JK Flip Flop.
5. Basic JK Flip Flop does not require any NOT Gate but Master JK Flip Flop use it.

Circuit of Master Slave JK Flip Flop

If we talk about the Circuit of the JK Flip Flop then it is always convenient to use the IC presented in Proteus ISIS. We'll show you the Circuit of Master Slave through ISIS but for the best concept and the working of the Circuit, we'll demonstrate the Logic Gate Circuit of Master Slave JK Flip Flop during the Simulation. Let's have a look at the circuit of Master Slave JK Flip Flop with IC:

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

When the condition of Master Slave Flip Flop is J=1 and K=1 then the values at Q  and Q' remains change according to the flow of clock.

Working Mechanism of JK Flip Flops

It is important to understand how Master Slave Flip Flop works. When the clock Pulse is set to be high, the circuit of Slave is isolated. The Slave circuit remains isolated until the Clock is high. At this position, the J and K have an effect at the output of the whole circuit. When we set the J as LOW and S as HIGH. The output of Switch 4 (Look at the picture below) will goes to the 2nd Input of switch 6. In this Condition, the Slave circuit copies the Master circuit. Similarly, when you change the values of J and K then you will Get different outputs according to the condition of clock.

Simulation od Master Slave JK Flip Flop in Proteus ISIS

Fire up your Proteus Software.

Material Required

1. Three input NAND Gate
2. Two input NAND Gate
3. Logic Toggle
4. LED-RED

• Go to Ground Terminal from the side of Proteus screen and choose Ground Terminal.
• Set the Ground terminal just after the LEDs.
• Place the NOT Gate just below the Three inputs NAND Gates.
• Connect the whole system through wires as reported by the following picture:

NOTE: You can also use the CLOCK instead of the Logic toggles in the experiment but this was not suitable for the demonstration purpose for me.

• Change the values of the toggle J,K and CLK one after the other to check the outputs.

This is the required circuit. Truss today we saw what are the Flip Flops, what are the JK Flip Flops. We saw the types of JK Flip Flops and leaned how can we perform the Practical simulation of Master Slave JK Flip Flops.

JK Flip Flop Circuit Diagram in Proteus

Hello Learner! I hope you are doing great. Welcome to another tutorial at The Engineering Projects. This blog is the part of series we have stated about the Digital Logic Circuits. Previous to this, we learned Implementation of SK Flip Flops in Proteus. at the present day, we'll seek the knowledge about the following points:

1. What are Flip Flops?
2. What are JK Flip Flops?
3. How can we record the Truth Table of JK Flip Flops?
4. What is the Procedure to Construct the circuit of JK Flip Flop through Logic Gates and IC circuit?

Moreover, we'll also have some useful bits of Information in Did you know Sections. Let' see the explanation of the concepts given above.

Flip Flops

The Flip Flops are the building blocks of many of  the Electronic Circuits. We define the Flip Flops as:

"The Flip Flops are the type of sequential Logic Circuits that are mainly made through the Logic Circuits and have the ability to receive, store, and show the output in the form of binary bits i.e, 1 and 0."

There are mainly four types of Flip Flops:

1. SR Flip Flops
2. JK Flip Flops
3. D Flip Flops
4. T Flip Flops

The main focus of this blog is JK Flip Flop so we'll discuss them in detail.

JK Flip Flops

JK flip Flops are the sequential Circuits and are the very much similar to SR Flip Flops. We introduce the JK Flip Flips as:

"The JK Flip Flops are the Universal Flip Flops containing two inputs, two outputs and a Clock in the Circuit. They have e the ability to avoid the invalid or Illegal condition of the Flip Flops."

The name of the inputs are said to be J and K respectively. Unlike SR Flip Flops ( where S stands for Set and R stands for Reset) the inputs of JK Flip Flops are titled autonomously. Somehow, related to the inventor of the JK Flip Flop "Jack Kilby".

DID YO KNOW???????????

JK Flip Flops are useful in many ways as: They have Low power dissipation. They are much Faster than their sibling Flip Flops.

]The output of the JK Flip Flops are named as Q and Q'. As the name implies , both the Outputs are opposite to each other. When Q is HIGH , the Q' is Low and same is the case with the opposite condition. The Truth Table Of JK Flip Flop is given next:

CLOCK	J	K	Q	Q’
High	0	0	Unchanged	Unchanged
Low			Unchanged	Unchanged
High	0	1	0	1
Low			0	1
High	1	0	1	0
Low			1	0
Low	1	1	1	0
High			0	1

There are two types of JK Flip Flop named as:

1. Basic JK Flip Flop.
2. Master-Slave JK Flip Flop.

Yet in this lesson, we'll make a clear idea about the Basic JK Flip Flop only. For best concepts, we'll not just observe the Circuit diagram of JK Flip Flop but we'll Construct a Circuit using different tools and Components in Proteus ISIS. We'll learn about the Formation of JK Flip Flop in two ways:

1. JK Flip Flop through Logic Gates.
2. JK Flip Flops through IC.

Rush toward your Proteus Software and learn how can you make this in just simple steps.

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

The JK Flip Flops are the better version of SR Flip Flops and are better than those just using a NOR Gate.

JK Flip Flop Circuit Diagram in Proteus

• Start your Proteus Software.
• Get the following material from the Pick Library through "P" button..

Material Required

1. 3 input NAND Gate.
2. 2input NAND Gate.
3. Logic Toggle.

• Get a Clock and set it in between two logic Toggles.
• JK Flip Flop Circuit Diagram in Proteus is shown in image given below:

• Pop the Play button to start simulation.
• Change the values of the inputs and observe the output at each gate. You will get the following table:

CLOCK	J	K	1	2	Q	Q’
High	0	0	Unchanged	Unchanged	Unchanged	Unchanged
Low			Unchanged	Unchanged	Unchanged	Unchanged
High	0	1	1	1	0	1
Low			1	1	0	1
High	1	0	1	1	1	0
Low			1	1	1	0
Low	1	1	1	1	1	0
High			1	1	0	1

Hence this is the required output.

JK Flip Flop IC (Integrated Circuit)

Due to the usability of JK Flip Flop, Proteus ISIS has added many JK Flip Flop IC. In this way, we do not need to design all the circuit. Instead we can simple using JK Flip Flop IC.Let's see how it will work:

Material Required

1. JK Flip Flop ( IC)
2. Logic Toggle
3. LED-red
4. Ground Terminal

• Place the JK Flip Flop IC at the working area.
• Connect Logic Toggles and clock at the respective ports.
• Add the Led at Q and Q' ports.
• Ground the LED's through Ground Terminals.

• Change the values of the Logic Toggles again and again and check that does you get the required output or not.

Easily available JK Flip Flop IC

Proteus also contain many other ICs of JK Flip Flop. Some of them are as follows:

1. 74LS107 that contain a Dual JK Flip Flop with CLEAR.
2. 4027B is an IC that is Dual JK Flip Flop.
3. 74LS73 contains Dual JK Flip Flop with CLEAR.
4. 74LS76 has Dual Flip Flop with PRESENT and CLEAR.

Truss, Today we recalled that what are the Flip Flops, what are its types, learned a great information about JK Flip Flops and designed its circuit in Proteus ISIS in two ways. Hopefully, you got the required pieces of particulars. in the next Lesson, we'll talk about the Master slave JK Flip Flops.

Introduction to Arduino UNO REV3

Hi Friends! Hope you’re well today. Happy to see you around. In this post, I’ll detail the Introduction to Arduino UNO REV3. Arduino Uno REV 3 is an Arduino board based on the microcontroller ATmega328P. It carries 14 digital I/O pins out of which 6 can be used as PWM outputs. Moreover, 6 analog input pins are available on the board and the clock frequency is 16MHz. Arduino UNO is one of the most used boards from the Arduino family. The robust and clean design helps you shape your ideas into reality. Know that Arduino UNO REV3 is an advanced version of Arduino UNO. The new version includes four solder pads JP2 attached with the pins PB4 to PB7 of the USB ATmega. Uno stands for one in Italian and this name was picked for the release of Arduino Software (IDE) 1.0. The version 1.0 of Arduino Software (IDE) and Uno board both are considered as the reference versions of Arduino, which evolved with time with new features. The UNO board is the first USB board from the Arduino family. Arduino is an open-source platform which means you can get a hold of Arduino boards and software and edit and modify them as per your requirements. Arduino IDE software is free to use for anyone, moreover, as you join this platform you can get help from the Arduino community. I suggest you read this post all the way through as I’ll detail the complete Introduction to Arduino UNO REV3 covering pinout, features, pin description, and applications. Let’s get started.

Introduction to Arduino UNO REV3

• Arduino Uno REV 3 is an Arduino board based on the microcontroller ATmega328P.
• It comes with 14 digital I/O pins out of which 6 can be used as PWM outputs.
• There are 6 analog input pins and the board’s clock frequency is 16MHz which is used for the synchronization of internal functions.
• Moreover, this board includes a power jack, USB connection, ICSP header, and reset button.

• In fact, it contains almost everything required to support the built-in controller. Simply plug this device with the computer using a USB cable or power it up with an AC-to-DC adopter or battery and start playing with it.
• The operating voltage is 5V while the input voltage ranges from 6 to 20 and the recommended input voltage ranges from 7 to 12V.

• Only 5 V is required to power up the board, which we can obtain using the USB port or external adopter, however, it can support an external power source up to 12 V which can be regulated and limit to 5 V or 3.3 V depending on the requirement of the project.
• Internal pull-up resistors are installed in the board that keeps the current under a certain limit. Know that too much increase in the current can make these resistors useless and can ultimately damage the entire project.
• The flash memory is 32KB while the EEPROM and SRAM are 1KB and 2KB respectively. The flash memory is the location where the Arduino program (sketch) is stored.
• While the SRAM is the memory used to produce and manipulates variables when it runs. The EEPROM is a non-volatile memory that keeps the code stored even when board power is removed.
• A reset pin is included in the board that resets the whole board when it is pressed and takes the running program to the initial stage. This pin comes in handy when the board hangs up in the middle of the running program, pressing this pin will clear everything up in the program and again runs the program from the beginning.
• This board carries a built-in regulation feature that keeps the voltage under control when the board is attached to the external device.

Arduino UNO REV3 Pinout

The following figure shows the pinout diagram of Arduino UNO REV3.

Arduino UNO REV3 Pin Description

Hope you’ve got a brief look into the Arduino UNO REV3. In this section, we’ll cover the pin description of each pin incorporated on the board.

Digital Pins

There are 14 digital pins incorporated on the board. You can use these pins as an input or output based on your requirement. These pins receive two values HIGH or LOW. When these pins receive 5V they are in the HIGH state and when they receive 0V they remain in a LOW state.

Analog Pins

There are 6 analog pins available on the board. These pins can receive any value compared to digital pins that only receive two values i.e HIGH or LOW

PWM Pins

Out of 14 digital I/O pins incorporated on the board, 6 are used as PWM pins. These pins generate an analog signal with digital means when these pins are activated.

SPI Pins

The board comes with an SPI communication protocol that is mainly used to maintain communication between the microcontroller and other peripheral devices like shift resistors and sensors. Two pins: MOSI (Master Output Slave Input) and MISO (Master Input Slave Output) are used for SPI communication between devices. These pins are employed to send or receive data by the controller.

I2C Pins

This is a two-wire communication protocol that comes with two pins called SDL and SCL. The SDL pin is a serial data pin that carries the data while SCL is a serial clock pin that is used for the synchronization of all data transfer over the I2C bus.

UART Pins

This board also supports UART serial communication protocol. It contains two pins Tx and Rx. The Tx is a transmission pin used to transmit the serial data while Rx is a receiving pin that is used to receive the serial data.

LED

There are four LEDs on the board. One is a built-in LED connected to pin 13 other is a power LED. And two are Rx and Tx LEDs which operate when serial data is transferred or received to the board.

Vin, 5V, GND, RESET

Vin……. It is the input voltage supplied to the Arduino Board. It is different from than 5 V we get through a USB port. Moreover, if a voltage is supplied through the power jack, it can be accessed through this pin. 5V……… This board contains voltage regulation ability. This board is activated using three ways i.e. USB, Vin pin of the board, or DC power jack. USB supports voltage around 5V while Vin and Power Jack support a voltage ranges between 7V to 20V. Know that, if a voltage is supplied through 5V or 3.3V pins, they will bypass the voltage regulation which ultimately damages the board if the voltage exceeds the certain limit. GND….. This is a ground pin. More than one ground pins are available on the board which can be used as per requirement. Reset… This pin resets the program running on the board. Instead of a physical reset on the board, IDE can reset the board through programming.

Arduino UNO REV3 Features

Microcontroller = ATmega328P Operating Voltage = 5V Digital I/O Pins = 14 PWM Digital I/O Pins = 6 Analog Input Pins = 6 Input Voltage (limit) = 6-20V Input Voltage (recommended) = 7-12V Flash memory = 32KB SRAM = 2KB EEPROM = 1KB Oscillator = 16MHz Size = 53x68mm Weight = 25g

Programming

• This board carries all specifications needed to run the controller. You can directly connect this board with the computer using a USB cable and send a lot of instructions to the board using Arduino IDE software. The programming language C or C++ is used to program the controller.
• It is important to note that Arduino comes with a Bootloader that is mainly used to burn the Arduino program which means you don’t require an external burner to burn the program inside the controller.
• The Arduino. IDE software is compatible with many operating systems including Windows, MAC or Linux Systems, however, Windows is preferred to run this software.

Difference between Arduino UNO and Arduino UNO REV3

• The Arduino Uno incorporates the ATMEGA8U2 USB microcontroller on board. While R3 board comes with an upgraded version of the USB controller ATMEGA16U2 on board.

• The Arduino Uno features an LED and resistor connected in series on pin 13. The R3 board buffers this LED/resistor using a unity gain operational amplifier. This is the separate op-amp that was not used in Arduino Uno.

• The Arduino UNO R3 board includes a diode across the USB ATmega reset pin pull-up resistor.
• The R3 board includes four solder pads (JP2) connecting to pins PB4 to PB7 of the USB ATMEGA. These solder pads are not present in Arduino Uno.

Arduino Uno REV 3 Applications

Arduino Uno is used in a wide range of applications. Following are some main applications of the board.

• Security and Defense System
• Embedded System
• Industrial Automation
• Digital Electronics and Robotics
• Weighing Machines
• Parking Lot Counter
• Traffic Light Count Down Timer
• Home Automation
• Emergency Light for Railways
• Medical Instrument

Don’t confuse the microcontroller with the Arduino board. Every Arduino board is a microcontroller but not every microcontroller is an Arduino board. Both devices are used for different purposes, however, the Arduino board is easy to learn that even a person with no technical skills can get hands-on experience with this device. That’s all for today. Hope you find this article helpful. If you have any questions, you can approach me in the section below. I’d love to help you the best way I can. Feel free to share your valuable suggestions and feedback around the content we share, so we keep producing quality content as per your needs and requirements. Thank you for reading the article.

4 Tips for Better Construction Job Bids

Hello Buddies, Welcome from the team of The Engineering Projects. We hope you are having a good day. In this article, you will investigate about four remarkable tips for a better job bit that will boost your chances to be hired. Construction is an emerging and fast-growing source of business. However, we cannot neglect that it is a very competitive field at the same time. In this ever-growing world, where the construction business is highly profitable and demanding, most people fail to get better construction jobs due to inaccurate bids. While construction bidding is not an easy task, better understanding and farsightedness can help you win more jobs.

What is construction bidding?

Construction bidding is the process through which you submit a proposal for a specific job. In other words, you send your proposal to a potential client. As simple as it may seem, writing an attractive proposal isn’t easy. Many companies have very unfavorable bid-hit ratios, which translates into wasted time and money. However, this process doesn’t depend entirely on luck. Understanding the process and working diligently can make your construction bidding more manageable and successful. When a client invites contractors to bid on a project, they often split it into different chunks. For example, one chunk of the job might be plumbing and another electrical work. Then, the client will invite various subcontractors to bid on tasks related to their specialties. This process is very smooth as it allows the owners and contractors to develop better relationships and continue their work. Similarly, it also helps the owners to get the best team of contractors for their construction project.

Tips for Submitting Better Construction Job Bids

Preparing a bid proposal for construction jobs takes a lot of time and effort. It requires full focus on understanding the client’s needs, estimating the costs for laborers and equipment, and then bidding. Even the smallest of mistakes can make you lose a highly profitable project opportunity. The following tips will help you in writing the best construction job bids.

Many people think that bidding on every job they encounter will increase their chances of getting work. However, that’s not the case. It will only utilize your energy and time with no fair results. Thus, bidding on every job you find is among the worst mistakes construction contractors make. A much more effective strategy is to bid less and bid on those jobs worth your consideration and time. Let’s assume you bid on a particular project without thinking and attend all pre-bid meetings and start taking subcontractor pricing. After analyzing the pricing and crunching the numbers, you realize that it doesn’t offer much profit to your team. So, the only solution at this point is to move on to another project. But what did all the effort, pre-bid meetings, and takeoffs cost you? It was a tremendous waste of time and resources. It can improperly impact your overall profitability as a company. Therefore, the best strategy is to identify the client’s needs and bid on those projects you can perform and give the best results. Before bidding, think about the past projects your company had won and delivered and came out with successful results. If the new projects are similar, bid on them.

?       Develop a positive reputation

General contractors always gauge your effort and professionalism based on the proposals you submit. An attractive proposal highlighting your ability to meet the client’s needs can help you win the job for the bid amount quickly. A good bid proposal is detailed. Take the time to carefully craft your messaging and offer within the proposal before submitting it. To be more precise, the proposal should be professional, comprehensive and accurate. To know more about writing a winning bid proposal for construction, head to bridgitsolutions.com. The company is highly reputable and has put together a great resource about crafting effective construction bids.  

?       Know when to submit the lowest bid

If a brand has no real competitive advantage over others, its chance of winning the bids becomes difficult. The same happens when you are new to the area and are surrounded by highly reputed and competitive companies. If you’ve nonetheless identified the project as one that will further your company’s goals, you may consider placing a relatively low bid. This strategy can help a lot as it attracts more contractors to get the work done at the lowest price. However, it should not be so low that you lose your profit – unless you’re willing to treat the project as a loss leader. However, some contractors value your skills and expertise more than the price. If you have a team of highly skilled professionals capable of managing the client’s needs, that constitutes a competitive edge they’ll likely consider when choosing a contractor.

?       Create accurate estimates

Taking accurate measurements is essential when calculating the appropriate bid. Inaccurate measurements and human errors can cause many problems as it misrepresents the total amount of labor and materials, which can have a devastating impact on your bottom line. The best way to create accurate estimates is by using good estimating software. An efficient software solution can speed up the process and provide error-free, precise, and accurate bids. Similarly, arithmetic errors leave a huge impact on the bid. So, using a calculator is better to ensure better measurements. However, robust construction bid software is the best way to ensure accurate measurements in less time. Choosing the best estimating software is also difficult when there are so many in the market. First of all, understand your needs and what you want the software to do for you. Then, do proper research and choose the best software solution for your goals.

Conclusion:

Preparing a competitive and winning proposal for a construction job requires time and effort. However, no matter how much time you put in, if you don’t have a proper proposal with accurate estimates, your efforts will go in vain. Thus, the tips mentioned above will help you understand the strategies of construction bidding and bidding for the right and winning proposal.

Implementation of SR Flip Flops in Proteus

Hello Learners! welcome from the team of The Engineering Projects. We hope you are having a productive day. We are working on a series of Blogs based upon the core knowledge about Digital Logic Gates and Circuits. In this tutorial, we'll know about the SR Flip Flops and after brief introduction we will simulate SR Flip Flops in Proteus. Let's have a glimpse on the topics of today:

• What are Flip Flops?
• What are the types of Flip Flop?
• How does we design the Truth Table of SR Flip Flops?
• What are further classes of SR Flip Flips?
• Implementation of SR Flip Flops in Proteus.

Flip Flops

Flip Flops are extremely important Circuits of Digital Logic Design. We Introduce the Flip Flops as:

"Flip Flops are type of sequential Logic Circuit that contain two stable states "Zero" and "One" (because of the binary system). It is often used as Storage device and each state of Flip Flop stores one bit." 

They are the building blocks of the Electronics and play an important role in the world of Logic Circuits. Being the Binary circuits, they are essential for the computation in the computer system. The Inputs of the Flip Flops are named as "S" AND "R" that stands for Set and Reset respectively. There are two Outputs of the Flip Flop called Q and Q'. As the name suggest itself, both the outputs are the Inverse of Each Other. the Flips Flop are sequential Logic Circuits that mean they use a Clock called as "CLK"  in the circuit. the Function of clock is to synchronize the circuit. The Phenomenon in which the clock signal is change its value i.e, from 0 to 1 or from 1 to 0, is called the edge of the clock.

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

Flip Flops are also called as Bipolar Multi-vibrator because they can store the both the Conditions of the Binary system.

When we say that Flip Flops are the Storage Devices, we mean that they does not only calculate the output from the present data, but they can also work with the data stored previously in the Flip Flops.  

Types of Flips Flops

When we talk about the types of Flip Flops, we consider mainly Four types of Flip Flops as follow:

1. SR Flip Flop
2. JK Flip Flop
3. D Flop Flops
4. K Flip Flops

These kinds are same in the composition of circuits, but the working, Construction and the results are different from each other. We'll Describe the structure of each of them along with the simulation for best concepts one after the other.

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

Flip Flops can maintain a binary state as long as there is power in the circuit, therefore can store the Data.

SR Flip Flop

The full name of SR Flip Flop is Set Reset Flip Flop. In this type of Flip Flop the Value of Output Q depends upon the Value of the "S" input. once the input of the SR Flip Flop goes high (When S and R are high) the output goes to infinity or undefined therefore this Circuit is used to  store the information.

Truth Table of SR Flip Flop

When we talk about the Truth Table of SR Latch, we find some unique behavior. The Interesting point about the SR Latch is when Set and Reset are LOW i.e, 0 then the value of the Output does not change. The circuit does not show any alternation. Moreover, when the values of inputs are HIGH, the output is undefined as discussed above. Hence the design of Truth Table of SR Flip Flop is as follow:

S	R	Q	Q’
0	0	No change	No change
0	1	0	1
1	0	1	0
1	1	Undefined	Undefined

  The SR Flip Flops are further classified into two main types:

1. Active High SR Flip Flops.
2. Active Low SR Flip Flops.

we'll learn about their details and the structure of the circuit.

Active High SR Flip Flops

The Active High SR Flip Flops are the one in which the Set input and the output terminal Q collaborate with each other. When the S is 0, the output Q is 1 and vise versa. We know that Q is always opposite to Q' hence we get the output as expected. Let's Look at the circuit of Active High SR Flip Flop and work at it in Proteus ISIS.

Active High SR Flip Flops in Proteus ISIS

• Fire Up your Proteus Software.

Material Required

1. AND Gate
2. NOR Gate
3. NAND Gate
4. Logic Toggle
5. LED-Red
6. Clock
7. Ground Terminal
8. Connecting Wires

• Click at the "P" button and Write AND Gate, NOR Gate, Logic Toggle, LED-Red, Clock one after the other and choose them through Enter button.
• Choose AND Gate from the Pick Library section and arrange two of them at the working area.
• Get two NOR Gates and arrange them just after the AND Gates.
• Get two Logic Toggles and Arrange them just before AND Gate for input.
• Choose two LEDs and fix them just after the NOR Gates.
• Ground each LED through ground Terminal Found in the Terminal modes at the left side of screen.
• Use a Clock in between AND Gates.
• Join all the components through wires just like the image given below:

Now Pop the Play button. Alter the Values of Input and observe all the outputs at each Logic Gate. You will get following Truth Table:

S	R	1	2	Q	Q’
0	0	0	0	No change	No change
0	1	0	1	0	1
1	0	1	0	1	0
1	1	Undefined	Undefined	Undefined	Undefined

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

The inputs of Active Low SR Flip Flops are denoted by a a bar , a complement or a "not" word along with their name.

Active Low SR Flip Flop

The Active Low SR Flip Flops have the same output as their twin Circuit Active High SR Flip Flop. The difference is in the construction of the circuit. We use the NAND Gate in the Construction of Active Low SR Flip Flop. all other arrangements and devices are same as the previous one.

Simulation of Active Low SR Flip Flop in Proteus ISIS

• In the above Circuit of Active High SR Flip Flop, pop the left click at gate 1.
• Left click>Delete the Gate 1.
• Repeat the same step with other gates as well.
• Add the NAND gate in all the places.
• Arrange the system again as shown in the figure below:

When we Test the Active Low SR Flip Flop we get the following outputs:

S'	R'	1	2	Q	Q’
0	0	0	0	No change	No change
0	1	1	1	0	1
1	0	1	1	1	0
1	1	Undefined	Undefined	Undefined	Undefined

Hence this is another form of SR Flip Flop. Consequently, we learned about the Flip Flops, we saw what are its types , saw the subclasses of the Flip Flop and designed two types of SR Flip Flops in Proteus ISIS. Stay tuned for the other tutorial in which we'll solve the problem of undefined conditions of Flip Flops.

How to Select the Right LMS Vendor for your Business?

Learning Management Systems have gained popularity with technological advancements.  The curiosity to learn NEW made the information available with just a few clicks away. That’s how e-learning was born! Now, it has become inevitable for every business to adapt to the trend. When it involves developing a course from scratch, you need LMS.  Well, by what norms do we identify LMS vendors for my business? Here are five checkpoints you should know when choosing an LMS vendor.

• The background

It is quite common when you are choosing an LMS vendor; you look for the price. Beyond the quote they are offering, you need to verify their track record. Ask the following questions to acquire the vendor’s level of the business.

1. How long has the LMS dealer been in the industry?
2. How many customers does the vendor have dealt with so far?
3. What are the evolving trends in LMS?
4. What are the common priorities of customers?
5. Which features of LMS are used most in recent times?

You can infer the quality of the LMS vendor in the business from his answers.

• The knowledge on e-learning

E-learning is the prime motive of the Learning Management System (LMS). If your LMS vendor doesn’t have enough knowledge about it, he is out of the game.  His leadership skills will show whether they (the company) have a stagnant product or have a room for innovation.  For example, Artificial Intelligence and Game-full thinking are the desirable features most learners and employees are looking forward to in their training modules and online courses.  The LMS you are purchasing must have at least the introductory version of these features so that you can up-level your course in years down the lane. [caption id="attachment_161291" align="aligncenter" width="300"] online education concept - e-learning word cloud on a vintage slate blackboard[/caption] Moreover, the publication of high-quality content will prove the vendor’s expertise in offering valuable information to prospects and clients.  Also, check for the technical aspects like Flash and SCORM in the LMS.

• Customer Relationship Management

Who they are is essential but how they treat the customers is significant.  The response timing, language, and patience to solve the issues are the qualities that will impact you as a customer from LMS vendors. Check for information about the team members and multiple customer support from their website. It will reveal their identity. Consider how they value customer satisfaction and deal with multiple test ticket numbers simultaneously. This little follow-up communication clarifies their persona to you.

• A Live Demo -Free trial

Although verbal information gives you an overview, a test drive will reflect the working of LMS. It is good to ask for a free trial or a live demo.  You can gain first-hand experience; thus, comprehending whether the product meets your needs or not. For example, if you intend to offer multi-lingual support to your global employees in online training, you need to ensure the LMS is enabled with it. Plus, enquire the LMS vendor on the scalability functions to fulfil your future needs. 

• Look for Client views

Testimonials, reviews, and case studies will give you the user experiences straight from the previous clients.  It would be best to get references from other companies who use LMS and consider their insights.  These existing customers will tell you information on how LMS vendors respond to the issues. Besides, it is essential you team up with an LMS provider who has solid financial health.  This is because vendors with constant cash flow can perform research and development to upgrade their product, thus offering you a better version. 

The Bottom line

The initial point to all your training and management needs starts with choosing the right LMS vendor. We hope all these details will narrow down your search for the appropriate LMS provider.
