Blinking of LED Using Arduino UNO

Hi !!!!

Here we are going to learn very very simple use of Arduino, that is blinking of a LED. Here we will do simplest project using Arduino. So, here we go....

COMPONENTS REQUIRED -

1. Bread Board
2. Arduino UNO
3. Jumper Wires
4. Power Source (5V) / Battery
5. Resistor (1K)

CIRCUIT PREPARATION -

Take bread board and Arduino. Connect the +5V from Arduino to the +Ve line on Bread Board and GROUND from Arduino to -Ve line on bread board.

Red Wire     : +5 V

Black Wire  : GROUND

 

 

Now put a LED on bread board. Connect the Anode (+ / Longer terminal) of led to the pin 13 of Arduino. Connect Cathode (- / Shorter terminal) to 1K ohm resistor and connect another terminal of resistor to the GND on breadboard.

 

Now our circuit is ready to work. 

Our next aim is to build the code. Let's make our code.

CODE -

int led = 13;  // led is connected to pin 13 of arduino, so it is given a name, led

void setup()   // this routine runs once when you press reset:

  

{

  

  pinMode(led, OUTPUT);  // initialize led pin as output pin

  

}

void loop()

  

{

  digitalWrite(led, HIGH);        // turn the LED ON

  

  delay(1000);               // Wait for 1000 millisecond(s)

  

  digitalWrite(led, LOW);          // turn the LED OFF

  

  delay(1000);              // Wait for 1000 millisecond(s)

}

Yurekaaaaaaaaaaaaaaaa.. !!!!

here we go... our project is working now !!!!
