LED Blinking using 555 Timer

Hello friends, hope you all are fine and having fun. Today I am going to share my new tutorial which is Sequential LED Blinking Using 555 Timer in Proteus ISIS. If you recall our one of previous tutorials, which was ‘Multiple LED Flashing Project Using 555 Timer in Proteus ISIS’, but in today’s tutorial we are going to take the same concept to a next level and we are going to make the LEDs blink in either ascending or descending order.

It is a very simple tutorial like the previous one, but the only change is, in this project we have added a Shift Register (4017) next to 555 Timer. 4017 is a Serial IN Parallel OUT Shift Register, which means, at input port it takes data in Serial manner and at output port it will give data in Parallel manner. All types of register needs a clock pulse to operate and this clock is provided by Timers or Micro controllers. In this project we will be using 555 Timer to generate clock pulse. 555 Times gives clock pulse at pin # 3 abbreviated as ‘Q’ pin. And this clock pulse is given at pin # 14 of Shift Register abbreviated as ‘CLK’ pin. Shift Register (4017) has total 15 pins. 2 input pins, 10 output pins. Input data is given at pin # 13, which is called ‘Enable’ pin and register shifts the data sequentially at its output pins. Shift register has 10 output pins which means it is a 10-bit shift register, which means it executes 10-bit data simultaneously. Now dear friends, let’s move towards the hardware of the project but as you know, practice makes a man perfect. Try to do it with your own hand so that, you get to know the practical applications of electrical components in person.

Dear friends, you can also Download the complete simulation of the Sequential LED Blinking Project using 555 Timer, by pressing on the button given below. So, let's get started with Sequential LED Blinking using 555 Timer in Proteus ISIS.

Sequential LED Blinking using 555 Timer in Proteus ISIS

• Weare gonna design a Project named LED Blinking using 555 Timer so let's first have a look at its block diagram.

• Threshold voltage for 555 Timer is 5 volts, and when voltages exceeds this level, 555 timer triggers and it generates a output pulse at its output pin which is ‘Q’ pin.

• While designing the circuit, First of all 555 Timer will come, secondly Shift Register (4017) will be connected with it and at the end we will plug LED's. The complete circuit flow diagram is shown in figure below:

• Now coming towards the designing of the project, first of all, place the components in your Proteus workspace, as shown below in image:

• Now Output pulse from 555 Timer is connected to input ‘CLK’ pin of Shift Register.
• Since the register being used is 10-bit, and its outputs are Q0~Q9. The pins Q0~Q5 are connected to LED's D6~D1 respectively.
• After that Register output pin Q6 is also connected to LED (D2) and it becomes parallel with Q4. Now LED, (D2) has 2 parallel inputs and it becomes HIGH (turns ON) if any of the two Inputs is HIGH.
• Next we connect the Register output pin Q7 to LED (D3) and then it becomes in parallel with Q3. After doing that LED, (D3) has 2 parallel inputs and it becomes HIGH, if any of the 2 inputs is HIGH.
• After doing that, now we connect register’s output pin (Q8) to LED (D4) and then it also becomes in parallel with Q2, and LED will start glowing if any of the 2 inputs will be HIGH.
• Now at the end, we connect Q9 to LED (D5), and then it becomes in parallel with Q1. Now D5 has 2 inputs (Q9 &Q1) and LED will glow if any of the 2 inputs will be HIGH.
• Now at the end, If you have connected all the components in exact order, and all the connections are OK then, the exact simulation will look like as shown below:

• Now if we run the Proteus simulation and observe it closely, then we will see that, 555 Timer is continuously generating PWM and the Shift Register set’s its output ports HIGH from Q0~Q9 respectively.
• First of all Register’s output pin # Q0 becomes HIGH and it send signal to LED (D6) and LED will start glowing. You can also observe this phenomenon in the image given below:

• Then pin # Q1 becomes HIGH and it send signal to LED (D5) and D5 starts glowing. This can be observed in the figure given below:

• Then register's output pin Q2 becomes HIGH and sends signal to LED (D4) and D4 starts glowing. This can also be observed in the figure given below:

• Then Register's output pin Q3 becomes HIGH and send signal to LED (D3) and this LED starts glowing. This stage can be seen in the figure given below:

• Then Register's pin Q4 becomes HIGH and sends signal to LED (D2) and this LED (D2) starts glowing. This process is shown in the image given below:

• And in the next step, Register gets its pin # Q5 HIGH and send signal to LED (D1) starts to glow. This process can be seen in this figure:

• This process keeps on going and when the Register;s next pin becomes HIGH, which is Q6, then it again sends signal to LED (D2) and it starts to glow, and so D3,D4,D5 will glow respectively, and this sequence of LED's blinking will continue, until you stop it manually or by yourself.
• In the beginning, when LED's Started to blink from Left to Right which was (D6 to D1) , this sequence is called Forward Sequence.
• After that, LED's started to blink from Right to Left which was (D1 to D6), this sequence is called Reverse or Backward Sequence.
• We can summarize this whole sequence into a tabular shape, and this table is given in the figure below:

• This process keeps on going and LED's keeps on glowing in a beautiful sequence. These type of projects are generally used for decoration purposes.

• So, that's all about Sequential LED Blinking Using 555 timer.

Alright friends, that's all from this post. I hope now you can easily design LED Blinking using 555 timer Project. In the coming tutorials, we will discuss something new regarding 555 Timer applications. Until than, Take Care and Be Safe !!! :)

LM317 Voltage Regulator in Proteus

Hello friends, hope you all are fine and having fun. In today's post we are gonna have a look at LM317 Voltage Regulator in Proteus. In the previous post, we have seen how to design a 5V Power Supply in Proteus ISIS, which I have designed using IC regulator 7805. Today I am going to share How to design LM317 Voltage Regulator Circuit in Proteus. This DC power supply is a variable one means you can set its output voltage to any level you want. In order to change its output value we have used a variable resistor and by changing its value you can change the output value. It is a basic level project and very simple but used as a base to design large industrial projects. In this project, we are going to control the speed of a DC Motor and the corresponding voltages, appearing across it. The reason for designing this variable DC power supply is that, when you are working on some engineering project then each electronic module has its own power level i.e. xbee module works on 3.3V while Arduino board works on 5V. So, there's a need to design such power supply which can provide variable voltages and we can set them according to our demand. So, for all Microcontrollers like Arduino or PIC Microcontroller or 8051 Microcontroller, I designed 5V Power supply using 7805 but for 3.3V modules like XBee, NRF24L01 etc I design this variable DC power supply using LM317. I hope now you got the importance of this LM317 Voltage Regulator.

To design this, we will be using LM317k. Basically, it is a Voltage Regulator IC. It has 3 pins. Pin # 2 is for input voltages, marked as VI. Pin # 3 is for output voltages, marked as VO, and pin # 1 is used for Regulating Voltages and it is marked as ADJ. Further, if you notice the circuit diagram, which is given in the figure, then you will see that pin # 1 is connected to a Potentiometer. Potentiometer is a Variable Resistor device and it is also known as Voltage Divider. The feature of this electronic device is that, we can adjust the voltage through it according to our own choice. It operates on 12 Volts and it gives us ease that, we can adjust its voltages from 0 to MAXIMUM (which is 12 volts in most cases). Further if we notice the circuit, then we will see that a LED is connected in parallel with a simple DC motor and a voltmeter is also connected in parallel with Motor to monitor the voltages appearing across it. Above information was a little demo about the individual components of the circuit, now let’s be practical and move towards Hardware and see how actually Electronic components respond. You should also have a look at Introduction to LM317, if you wanna read all the basics about it. So let's get started with LM317 Voltage Regulator in Proteus:

LM317 Voltage Regulator in Proteus ISIS

• You can download this complete LM317 Voltage Regulator simulation by clicking the below button but I recommend you to design it on your own so that you learn most from it.

Download Proteus Simulation

• First of all, place all the components in Proteus workspace, as shown in image:

• A 12-Volt DC supply is provided to input pin (# 2) of LM317 and potentiometer is connected to Adjustable pin of LM317, which is, pin # 1.

• At output pin we have connected DC Motor and a Voltmeter is also connected in parallel with Motor.

• The complete circuit, ready for simulation is shown below in image:

Stage # 1

• Set the potentiometer at 0% and run the simulation, you will notice that Motor will rotate very slowly in clock-wise direction and 1.25 volts will appear on the voltmeter across it. If all the connections are OK, and when you will run the simulation, LM317 Voltage Regulator simulation will look like as shown in the image below:

Note:

• If you don't want to use the variable resistance, then you should use this LM317 Calculator to get value of your second resistance.

Stage # 2

• Now, set the potentiometer value to 11% and you will see that, Motor will start to rotate with a faster rate and on voltmeter scale, we will see 6.40 volts. In this setting, the interesting thing is, LED will start to Flash and it will turn ON & OFF automatically. This phenomenon can be seen in images below:

• Stage # 2 is our transient stage. When the potentiometers setting is below 11%, voltage appears across the motor and it also rotates but LED doesn’t glow. On the other hand, when potentiometers setting is above 11%, then LED glows continuously while motor also rotates as before, and voltmeter also gives some particular values of voltages appearing across the motor.

Stage # 3

• Now at final stage, set potentiometer to 100% and you will observe that motor is rotating with full speed and voltmeter reading will be 10.6 volts while LED is glowing continuously. This stage of the simulation can be seen in the image below:

Now, we can conclude that, LM317 is the monitoring device of this circuit. We can set the value of potentiometer according to our own choice and by this, the speed of motor can be controlled and also the corresponding voltages, appearing across it.

Here's the video in which I have given the detailed introduction of LM317 and have also run its simulation:

Alright friends, that's all for today and I hope now you can easily design this LM317 Voltage Regulator. In the next post, I have discussed DC Motor Drive circuit in Proteus ISIS . Till than take care and be safe !!! :)

Angle Control of Servo Motor using 555 Timer in Proteus ISIS

Hello friends, hope you all are fine and enjoying. Today we are going to share our new project’s tutorial which is Angle Control of Servo Motor using 555 Timer in Proteus ISIS. It is a very simple but a bit technical project. This project has various applications both in industry and in small educational projects.

Servo motor is a DC operated motor and it is available in various sizes and powers. Generally the servo motor used in basic projects, is named as micro servo motor. It is of small size and low power rating. But as I stated earlier that it needs dc supply to operate but it also needs a continuous pulse train to operate and this pulse is commonly generated by some sort of timers or micro controllers. Since my today’s project tutorial (Angle Control of Servo Motor using 555 Timer in Proteus ISIS) is of basic level so, we will be using 555 timer to generate the continuous pulse train or PWM. Now let’s move towards hardware but dear friends, always remember that to become a technical person, you must have to perform technical work by yourself.

Angle Control of Servo Motor using 555 Timer in Proteus ISIS

• First of all, place the components in your Proteus workspace, as shown below in image.

• A 555 timer is an 8 pin IC. Pin # 6 is called threshold pin and for 555 timer threshold level is 5 volts.

• So, 555 timer will trigger above 5 volts and it will generate output which can be collected from pin # 3 represented as ‘Q’ which is output pin of 555 timer.
• After that the output pulse is sent to servo motor through a Transistor which is BC547.
• BC547 is basically a NPN transistor and the pulse signal is sent to servo motor through its Emitter.
• The full angle deflection of servo motor is from -180 degrees to +180 degrees. It can’t rotate through full 360 degrees. Now it’s your own choice that either you want to rotate the motor at one particular angle or at multiple angles or to get full rotation.

• Since in this tutorial (Angle Control of Servo Motor using 555 Timer), we are going to get full deflection of motor so, we have inserted 2 switches in the circuit. The complete circuit will look like:

• Switch # 1 will rotate the servo motor to 180 degrees in anti-clockwise direction. We will press the button only once and when the motor completes its rotation, it will automatically stop.

• After that if we press the switch # 2, then it will rotate the servo motor in clockwise direction and again after completing the angle, motor will again stop.

• If you have connected the components in correct order and when you will run it, the exact simulation will look like as shown:

• Sonow, if you have a close look on the above two iages then you can see in theState # 1 image I have pressed the left button and the servo motor is moved to -90 degree, this -90 is also mentioned in the green LEDbox just below servo motor.
• And in State # 2, I have pressed the right button and thus the motor is moved to +90 degrees. That's how it will work.
• You can Download the simulation of Angle Control of Servo Motor Project Using 555 Timer in Proteus ISIS, by clicking on below button:

Download Angle Control of Servo Motor Project using 555 Timer

Alright Friends, that's all for today, In the coming posts, we will discuss few more such projects. Till than, take care and be safe !!! :)

Display ADC value on LCD using Arduino

Hello friends, hope you all are fine and having good life. In today's project, we will see how to display ADC value on LCD using Arduino in Proteus ISIS. Its quite a simple project in which we are gonna measure the voltage of ADC pins and then will display them over to LCD. The microcontroller I am using in this project is Arduino. The simulation is designed in Proteus ISIS. IF you are working on PIC Microcontroller then you should have a look at How to Display ADC value on LCD using PIC Microcontroller in Proteus ISIS.

Arduino has 10 bit ADC pins so whenever you apply voltage on these pins it will give you a value ranging from 0 to 1023 depending on the voltage provided. One can easily get this value using a simple function in Arduino analogRead(); but the real problem is to convert this analog value into the actual voltage present on the pin. Suppose you are using A0 pin of arduino and you are providing 3.3V over to this pin, now when you use this analoagRead() function then it will give you some value say 543, but you wanna know what's the actual voltage at this pin which is 3.3V so now converting this 543 to 3.3 is a bit tricky part. It's not difficult but involves a little calculations, which I am gonna cover today in detail. Before going any further, make sure you have already installed the Arduino Library For Proteus, if not then first do it because without this library you won't be able to use Arduino board in Proteus. So, let's get started with How to Display ADC value on LCD using Arduino.

Display ADC value on LCD using Arduino in Proteus ISIS

I have divided this tutorial on How to Display ADC value on LCD using Arduino in few steps, follow these steps carefully and if you get into some trouble then ask in comments and I will try my best to resolve them, all the materials are provided at the end of step 1 for download but I suggest that you design your own so that you do mistakes and learn from them. Moreover, you should also have a look at these Arduino Projects for Beginners. Anyways, let get started:

Step1: Circuit Designing in Proteus

• First of all, I have designed a circuit in Proteus for Displaying ADC value on LCD using Arduino.
• In this circuit, I have used two transformers which I have named as Potential Transformer and Current Transformer. I am supplying 220V to these transformers which is then converted into 5V.
• I have set the turn ratio of these transformers such that they give maximum 5V at the output.
• Now,rest of the circuit is simple, I have just connected the LCD with Arduino so that we could display these ADC value over to LCD.

Note:

• Before connecting any pin to ADC, make sure that the output should be less than 5V. Otherwise, there's a chance that the pin burnt out.
• If you don't know about LCD then read Ciruit Designing of LCD with Arduino in Proteus.
• You should also download this New LCD Library for Proteus.

• Here's the circuit diagram of displaying ADC value on LCD using Arduino in Proteus ISIS:

• You can download the Proteus Simulation and the Arduino hex file for Displaying ADC value on LCD using Arduino by clicking on below button:

Download Proteus Simulation and Arduino Hex File

• It's quite simple and self explanatory. After designing the circuit diagram, now let's move to second step, which is code designing for Displaying ADC value on LCD using Arduino.

Step 2: Arduino Code Designing

• Now copy the below code and paste it into Arduino software. Compile your code and get the Arduino hex file.
• If you dont know How to get the hex file from Arduino then read Arduino Library for Proteus, I have explained it in detail there.

#include <LiquidCrystal.h>
#define NUM_SAMPLES 10

int sum = 0;
unsigned char sample_count = 0;
float voltage = 0.0;

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
const int PT = A0;
const int CT = A1;
float Cur;
float Vol;
float Power;

void setup() {
// set up the LCD's number of columns and rows:
lcd.begin(20, 4);
// Print a message to the LCD.
lcd.setCursor(6,1);
lcd.print("Welcome To");
lcd.setCursor(5,2);
lcd.print("Energy Meter");
//delay(5000);
lcd.clear();

Constants();
}

void loop() {
lcd.setCursor(0, 2);
ShowVoltage(9, 0, PT);
Vol = voltage;
ShowVoltage(9, 1, CT);
Cur = voltage;
Power = Vol * Cur;
lcd.setCursor(7,2);
lcd.print(Power);
}

void Constants()
{
lcd.setCursor(0,0);
lcd.print("Voltage: ");
lcd.setCursor(0,1);
lcd.print("Current: ");
lcd.setCursor(0,2);
lcd.print("Power: ");
lcd.setCursor(14,0);
lcd.print("V");
lcd.setCursor(14,1);
lcd.print("A");
lcd.setCursor(12,2);
lcd.print("W");
}

void ShowVoltage (int x,int y, unsigned int value)
{
while (sample_count < NUM_SAMPLES)
{
sum += analogRead(value);
sample_count++;
delay(10);
}

voltage = ((float)sum / (float)NUM_SAMPLES * 5.015) / 1024.0;
lcd.setCursor(x, y);
lcd.print(voltage);
sample_count = 0;
sum = 0;
}

• The code is quite simple and self explanatory, the only difficulty is in ShowVoltage function. In this function, I have first taken an average of 10 ADC values and after that I have applied a simple formula over it and then it will start start giving the voltage value which I have simply displayed over the LCD.
• Now everything's done, so Get your Hex File from Arduino Software and let's check the results whether it displayed ADC value on LCD using Arduino or not

Step 3: Result

• We have designed the electronic circuit in Proteus and have also designed our code and uploaded the hex file in Arduino.
• Now press start button and you will see something like this:

• Now if you compare the voltages in voltmeter and on LCD, you can see they are exactly the same. You can check the value of variable resistor and the values in LCD will also change as the voltage in voltmeter change.

That's all for today, hope I have conveyed some knowledge today and now you can easily Display ADC value on LCD using Arduino. In the next post we will explore more Arduino features. Till then take care and have fun !!! :)

LED Flashing Project with 555 Timer in Proteus

Hello friends, hope you all are fine and enjoying life. In today's tutorial, I am gonna show how to do LED Flashing Project with 555 Timer in Proteus ISIS. Its quite a simple project and usually done by engineers in their first or second semester. I have done this project in my first semester and have learned quite a lot from it. I recently done it on Proteus so thought of sharing it with you guys. It will also work on hardware as I have tested it. In this tutorial, we will first have a look at How to do single LED Flashing with 555 Timer in Proteus ISIS. And afterwards, we will also see how to flash two LEDs with 555 Timer in Proteus ISIS. Its quite simple and anyone one with basic knowledge of electronics can design it in his first attempt. Still if you get into any trouble, then ask in comments and I will try my best to resolve your issues, but I don't think its gonna happen as its quite basic. So let's start with this project:

Single LED Flashing Project with 555 Timer in Proteus ISIS

• First of all, copy these components from the Proteus components library:

• After selecting these components, now design a circuit in Proteus as shown in the below figure:

• Now when you click on RUN button in PRoteus ISIS, the LED will kep on flashing,it will go ON for 1 sec and then go OFF as shown in below figures.
• State # 1 is showing the OFF state of LED while the State # 2 is showing the ON state of LED.

• So, it will keep on flashing unless you Stop the Proteus ISIS simulation.
• You can download this simulation by clicking on the below button.

Download Single LED Flashing with 555 Timer in Proteus

Double LED Flashing Project with 555 Timer in Proteus ISIS

• In the above portion, we have seen how to flash a single LED with 555 Timer in Proteus ISIS, now let's flash two LEDs with 555 Timer in Proteus ISIS.
• First of all design a circuit as shown in below figure:

• As you can see its quite similar to the above project for single LED flashing with 555 timer in Proteus ISIS but has small changes in thhe values of resistor.
• So, now when you hit RUN button on Proteus ISIS then these LEDs will start flashing one after another, means when first LED is ON then the second one will be OFF and vice versa.
• Below figures are showing their ON OFF states:

• State # 1 is showing the OFF state for both the LEDs, while State # 2 is showing the ON state for first LED and OFF state for second and in third State first LED is OFF while the second LED is ON.
• So, this simulation will work in this way, if first LED is ON then the second one will be OFF and vice versa.
• You can download this second simulation by clicking on the below button:

Download 2 Led Flashing Project with 555 Timer in Proteus

That's all for today, in the coming post we will have a look how to design a traffic signal flasher with 555 timer in Proteus ISIS, which is gonna be quite exciting tutorial, so let's meet in the next tutorial. Till then take care and have fun !!! :)

Installation of Arduino driver in Windows

In today's tutorial, we are going to see how to install Arduino driver in Windows. In the previous post, we have seen what is Arduino? and why is it so popular and whats its use? Now, afer getting the basic knowledge of Arduino, the next step you need to do is to install Arduino driver in your computer so that it got recognized by your computer as Arduino. If you don't install the Arduino driver in Wndows then you won't be able to program Arduino using Arduino software.

tis tutorial is quite basic and is for the newcomers, who wants to start working on the Arduino software, if you have already run some codes on your Arduino then its not for you. You can skip it. Anyways, It's quite easy and it won't take much time. So let's get started with it.

Installation of Arduino driver in Windows

• First of all, download the Arduino software from Arduino official website. Download the most reent version of Arduino software, which is 1.6.3 while writing this post.
• After downloading the software, now plug your Arduino USB into computer.
• You will hear a small beep and Windows will try to intall the driver itself, but finally a yellow box will appear on the taskbar saying driver can't be installed.

Note:

• If you haven't bought your Arduino UNO yet, then you can buy it from this reliable source:

• So, now right click on your My Computer, open properties, then click on Device Manager and you will get a Window as shown in below figure:

• Now click on Other devices which is encircled in the above figure and you will get a new element named as Unknown device. This Unknown device is actually our Arduino UNO on which we are going to install the driver.
• Right click this Unknown device and then click on the Update Driver Software.

• As you click on it, it will give you two options so click on the below one which says Browse My Computer For Driver Software.

What is Arduino ?

Hello friends, today I am posting a very basic tutorial on what is Arduino ??? In this tutorial I am gonna explain the basics of Arduino for the beginners. I am writing this tutorial because I got a lot of requests from the engineers in which they ask questions like what is Arduino ? What's the difference between Arduino and PIC? How to use Arduino? etc etc. So I thought of writing this topic. It's a very basic tutorial so if you are already familiar with this board and know the answer of this simple question What is Arduino ??? then you can skip this tutorial but again you must read it once, may be you get something out of it. :)

I have posted a tutorial on Arduino Projects, in which I gave all the links of Arduino projects and tutorials posted on my blog, that's another reason for posting this tutorial. I am treating that Arduino Projects page as an ebook on Arduino so I am gonna post everything about Arduino as much as I can. And an ebook must have an intro chapter, which will be this one. So, let's get started.

What is Arduino ???

• Arduino is nothing but a simple microcontroller board which is normally used in engineering projects where there's a need to automate something.
• You can interface sensors with this board, can drive motors with this board, can plug switches in it etc.
• In old ages ( not old enough :P ), people used simple switches for turning ON a bulb so like you click the switch and the bulb is ON, it was quite a simple circuit, after that relays are invented and then engineers used 555 timer circuits in order to turn ON lights on some specific time. But the 555 timer circuits are quite big in size, so finally engineers discovered Microcontrollers in which there are simple OUTPUT and INPUT pins, so now if you want to turn on light at some certain time then you just simply plug the blub on output pin of microcontroller and then do some programming and add a timer to automatically turn on the bulb.

• So, the benefit of microcontroller is the circuit is quite simple and small in size.Moreover, its flexible, suppose you want to change the time of turning ON bulb then what you need to do is simply change the coding and it will be changed, but in 555 timer circuits you need to change the components in order to do so.
• Now, we know the use of microcontroller and also their benefit but thing is what is Arduino ??? In microcontrollers like PIC or Atmel, there's a small drawback.
• Suppose you want to work on PIC then you have to first design its basic circuit also need to design a power circuit to supply power to it and after that in order to upload the code in it, you have to buy a programmer/ burner as well. So, first of all you need to write the code for PIC Microcontroller and after that you need to upload code in it using a programmer and then plce PIC microcontroller back into the circuit and test, which is quite lengthy plus also got hectic when you are working on some project because you have to test code again and again.
• By the way, now advance programmers like PICkit2 and PICkit3 can be plugged on board but still you have to design the basic circuit so coming to bottom line, in order to do project with PIC or Atmel microcontroller you have to do soldering etc.
• But that's not the case with Arduino Board, Arduino has built in programmer and the basic circuit in it. So what you need to do is simply plug in Arduino with your computer via usb cable, get its software and start uploading code and also start testing.
• So, you don't need to plug unplug or do anything, simply upload the code and test. Moreover, it also has some very efficient tools using which you can test your output as well quite easily. Arduino board also has the pins on which you can simply plug your devices and can turn them ON or OFF. So, hats off to Arduino team for providing us a simple board which has everything on it.
• Another advantage of Arduino is that, because of its popularity all the electronic components also have the Arduino libraries which are free and using them you can operate that electronic component quite easily with Arduino. Its open source and hence its developing day by day.

Types of Arduino Boards

• There's a long range of Arduino boards available online, the basic Arduino board is named as Arduino UNO which is most widely used in projects.
• Arduino UNO has total 13 digital pins and 6 analog pins which are used for connecting sensors with them.
• Suppose you have a project in which you want to interface 30 sensors, then what you need to do ?? Now you need to buy another Arduino board named as Arduino Mega 2560. This board has around 70 pins on it which can be used as output or input and hence you can plug your sensors quite easily.
• Moreover, Arduino have also developed different shields like Arduino Ethernet shield. Using this shield you can provide internet access via Ethernet to your project.
• Then they have Arduino Wifi shield which is used for providing Wifi access to your project.
• They have also developed Arduino GSM shield for GSM or GPRS purposes, in short there's a wide range of Arduino boards available online.
• So which Arduino board you need to buy depends on the requirements of your project.

How to use Arduino ??

• Now I think you have got the basic idea of what is Arduino ? and why is it so popular ? So now lets have a look at how to use Arduino.
• When you order for your Arduino board, you will get a package similar to the image below:

• Along with this box, you will also have the USB cable, now take your Arduino board out of this box and plug the cable in it, connect the Arduino with your computer and you are ready to start working on it.
• In order to connect Arduino with your computer you have to install the Arduino drivers in Windows.

That's all for today, hope I have conveyed some knowledge and you now know the basics of Arduino i.e. what is Arduino ? and why to use Arduino.

Arduino Projects

Hello friends, I hope you all are fine and having fun with your lives.Today I am not gonna post a new topic or tutorial, instead I am going to arrange all my Arduino Projects and tutorials in this post, as its better to have all of them in one place. I recently posted a PIC Microcontroller Projects post and it was highly appreciated by the followers so I thought to do the same with Arduino as well because I have posted more Arduino projects as compared to PIC Microcontroller. I will post all the Arduino Projects & Tutorials links below in sequence i.e. from easy to pro level so if you are a new user and want to get command over Arduino projects then read all of them one by one. Moreover, I will also keep on updating this post whenever I am gonna add any new Arduino Project or Tutorial. If you feel problem in any of the below tutorials then ask in comments and I will try my level best to solve your queries. As I always say learning is all about practise and patience. So while doing Arduino Projects, you have to be patient and practical, don't just read these articles, always test these arduino Projects and tutorials. Because when you practically perform some project then you will do mistakes and get the chance to learn from them. You should also have a look at these Arduino Project for Beginners.

Arduino Introductory Tutorials

If you have already run your first code on Arduino then you can skip this section. This section is for the beginners who don't know anything about Arduino. I have explained in detail how to get started with Arduino board and at the end of this section, you will have the complete idea of how Arduino works and how to program arduino. You must visit the Official Arduino Site and join their forum because they have posted a lot of Arduino Projects there.

Arduino Tutorials - Basics

What is Arduino ??? Here's our first tutorial where I have explained the very basics of Arduino i.e. what is Arduino and how to use it? Arduino Vs Raspberry Pi In this tutorial, I have explained the difference between Arduino and Raspberry Pi in detail. I have discussed their Pros and Cons in detail. So, give it a try if you are confused in choosing between them.
