BLINKING OF LED

In this tutorial we will teach you how to Blink Led with Arduino UNO / Nano.

COMPONENTS USED :

SR NO

COMPONENT NAME

QUANTITY

1

Arduino Board(Uno or Nano) 1
2 LED

1

Schematic Diagram :

Code :

void setup()

{

// initialize digital pin 13 as an output.

pinMode(13, OUTPUT);

}

// the loop function runs over and over again forever

void loop()

{

digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)

delay(1000);                  // wait for a second

digitalWrite(13, LOW);   // turn the LED off by making the voltage LOW

delay(1000);                  // wait for a second

}
