* <div style="margin-left:0cm;margin-right:0cm;">Basic knowledge of Electronics</div>
* <div style="margin-left:0cm;margin-right:0cm;">Basic knowledge of writing a''' C''' or''' C++''' Program</div>
* <div style="margin-left:0cm;margin-right:0cm;">'''Arduino UNO Board''' with''' USB''' power cable</div>

|-
| style="border:1pt solid #000000;padding:0.106cm;color:#000000;" |
| style="border:1pt solid #000000;padding:0.106cm;" | Let us open the''' Arduino IDE''' to write our first program.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Point to the menu bar
| style="border:1pt solid #000000;padding:0.106cm;" | Here, we can see various menus in the '''Menu''' bar.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Point to the sketch file name on the top bar

<div style="color:#000000;"></div>

<div style="color:#000000;"></div>
| style="border:1pt solid #000000;padding:0.106cm;" | In '''Arduino''' environment, each program is saved as''' Sketch'''.

By default, it creates the name as '''Sketch underscore''' and a name.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Point to File >> Save menu
| style="border:1pt solid #000000;padding:0.106cm;" | You can change the name by clicking on '''File '''and then on '''Save'''.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Type '''BlinkLed '''in filename
| style="border:1pt solid #000000;padding:0.106cm;" | Type the filename as '''BlinkLed. '''

Now click on the '''Save''' button.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Point to the default code
| style="border:1pt solid #000000;padding:0.106cm;" | This is the default program environment with two empty functions -

'''void setup''' and''' void loop.'''
|-
| style="border:1pt solid #000000;padding:0.106cm;color:#000000;" |
| style="border:1pt solid #000000;padding:0.106cm;" | Now, we will write an''' Arduino''' program to''' '''blink the '''LED.'''
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Show the Window with the IDE and Board side by side
| style="border:1pt solid #000000;padding:0.106cm;" | I have placed my '''IDE''' and the''' Arduino board''' side by side.

This will help us to see the execution of the program and the output in the '''board'''.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | <div style="color:#000000;"></div>

<div style="color:#000000;"></div>

<div style="color:#000000;"></div>

Point to the pin number 13 with the marker
| style="border:1pt solid #000000;padding:0.106cm;" | For this''' LED''' program, I want to blink pin number 13.

It is a '''digital input/output pin''' connected to this''' LED''' internally.

Notice the highlight with the marker.
|-
| style="border:1pt solid #000000;padding:0.106cm;color:#000000;" |
| style="border:1pt solid #000000;padding:0.106cm;" | Now, we have to write our code.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Highlight the Void setup() function

<div style="color:#000000;"></div>

<div style="color:#000000;"></div>

<div style="color:#000000;"></div>

<div style="color:#000000;"></div>

<div style="color:#000000;"></div>

Type,

pinMode(13, output)
| style="border:1pt solid #000000;padding:0.106cm;" | '''void setup''' function stands for setting up a''' microcontroller'''.

In our case, pin number 13 has to be set up first.

To do this, we will use an in-built function called''' pinMode'''.

It has two parameters - '''pin number''' comma''' mode'''.

So, type''' pinMode open brackets 13 comma output close brackets semicolon'''
|-
| style="border:1pt solid #000000;padding:0.106cm;color:#000000;" |
| style="border:1pt solid #000000;padding:0.106cm;" | Why should we keep the mode as '''output'''?
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Highlight the code
| style="border:1pt solid #000000;padding:0.106cm;" | This is because the pin number 13 is internally connected to''' '''the '''LED.'''

It will glow when the voltage is high but it will not glow when the voltage is zero.

We have to configure mode as '''‘output’''' to serve voltage to the '''LED'''.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Point to void loop()
| style="border:1pt solid #000000;padding:0.106cm;" | Next we will write code to the''' void loop''' function.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | <div style="color:#000000;"></div>

<div style="color:#000000;"></div>

<div style="color:#000000;"></div>

<div style="color:#000000;"></div>

Type,

digitalWrite(13, HIGH)
| style="border:1pt solid #000000;padding:0.106cm;" | Before we blink a '''LED''', let us glow a '''LED'''.

There is a function called''' digitalWrite''' which will write to a digital pin.

This function has two parameters as''' pin number''' and''' value''' or''' state'''.

Already, we know the pin number as 13. The value should be '''HIGH''' or '''LOW.'''

So, type: '''digitalWrite open brackets 13 comma HIGH close brackets semicolon'''

We want to glow the '''LED'''. So, the voltage should be high.
|-
| style="border:1pt solid #000000;padding:0.106cm;color:#000000;" |
| style="border:1pt solid #000000;padding:0.106cm;" | That's all. The code is very simple.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | <div style="color:#000000;"></div>

<div style="color:#000000;"></div>
| style="border:1pt solid #000000;padding:0.106cm;" | Next step is to compile the program.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Click on the Tick icon

<div style="color:#000000;"></div>

<div style="color:#000000;"></div>

<div style="color:#000000;"></div>

<div style="color:#000000;"></div>

<div style="color:#000000;"></div>

Highlight the compilation status
| style="border:1pt solid #000000;padding:0.106cm;" | Click on the''' Tick icon''' on the Menu bar to verify the program.

This will compile our program into binary format which is understandable by the '''microcontroller'''.

You can see the compilation status at the bottom of the '''IDE'''.
|-
| style="border:1pt solid #000000;padding:0.106cm;color:#000000;" |
| style="border:1pt solid #000000;padding:0.106cm;" | Next we need to upload the program to the '''microcontroller'''.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Click on right arrow button
| style="border:1pt solid #000000;padding:0.106cm;" | Click on''' Right arrow button''' on the''' menu bar''' to upload.

Alternately, you can select''' Sketch''' menu and then''' upload'''.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Point to TX RX blinks
| style="border:1pt solid #000000;padding:0.106cm;" | You can see the''' TX RX''' blinks for a while. This indicates the transmission is '''ON'''.

Now you can see the''' LED''' is glowing.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Modify the program by typing,
| style="border:1pt solid #000000;padding:0.106cm;" | How to turn off the '''LED'''?

We have to modify this program such that the second parameter value is '''LOW'''.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Type,

digitalWrite(13, LOW)
| style="border:1pt solid #000000;padding:0.106cm;" | So, type: '''digitalWrite open brackets 13 comma LOW close brackets semicolon'''
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Compile and upload the program
| style="border:1pt solid #000000;padding:0.106cm;" | Now, let us '''compile''' and '''upload''' this program.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Point to the LED
| style="border:1pt solid #000000;padding:0.106cm;" | You can see the''' LED''' is off now.
|-
| style="border:1pt solid #000000;padding:0.106cm;color:#000000;" |
| style="border:1pt solid #000000;padding:0.106cm;" | We know how to turn''' ON''' and''' OFF''' the''' LED'''.
|-
| style="border:1pt solid #000000;padding:0.106cm;color:#000000;" |
| style="border:1pt solid #000000;padding:0.106cm;" | Next we will modify the program to make the''' LED''' to blink.

That is '''ON''' and '''OFF''', with one second interval.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Modify the program,
| style="border:1pt solid #000000;padding:0.106cm;" | We will change the program as shown:

'''Delay''' is a built in function which pauses the program for certain amount of time.

I will type:''' delay open brackets comma 500 close brackets semicolon'''

Here 500 means, 500 milliseconds, that is, half a second of delay.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Type,

digitalWrite(13,LOW)
| style="border:1pt solid #000000;padding:0.106cm;" | Next, type as '''digitalWrite open brackets 13 comma LOW close brackets semicolon'''

This makes the digital pin 13 to '''OFF''' mode.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Type,

delay(500);
| style="border:1pt solid #000000;padding:0.106cm;" | How long we want to turn it '''OFF'''?

Type:''' delay open brackets 500 close brackets semicolon'''

Again, we want to '''OFF''' it for 500 milliseconds.
|-
| style="border:1pt solid #000000;padding:0.106cm;color:#000000;" |
| style="border:1pt solid #000000;padding:0.106cm;" | Let me explain the''' Void loop''' program line by line again.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Point to code line by line
| style="border:1pt solid #000000;padding:0.106cm;" | '''Void loop''' is an infinite loop and it will execute continuously.

The pin number 13 connected to the '''LED''' will be in '''HIGH''' state for 500 milliseconds .
And then in the '''LOW''' state for 500 milliseconds.

This program is executed repeatedly in the loop.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Click upload
| style="border:1pt solid #000000;padding:0.106cm;" | Let us upload the program.
|-
| style="border:1pt solid #000000;padding:0.106cm;" | Point to the LED (24:48)
| style="border:1pt solid #000000;padding:0.106cm;" | We can see our''' LED''' is blinking.
|-
| style="border:1pt solid #000000;padding:0.106cm;color:#000000;" |
| style="border:1pt solid #000000;padding:0.106cm;" | This brings us to the end of this tutorial. Let us summarise.
