Blinking LED

Description

Use the Arduino to control a light emitting diode and make it blink in different rate.

Components Used

• Light Emitting Diode (LED)
• Resistor

Arduino Code

/*
  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.
 
  This example code is in the public domain.
 */

void setup() {               
  // initialize the digital pin as an output.
  // Pin 13 has an LED connected on most Arduino boards:
  pinMode(13, OUTPUT);    
}

void loop() {
  digitalWrite(13, HIGH);   // set the LED on
  delay(2000);              // wait for two seconds
  digitalWrite(13, LOW);    // set the LED off
  delay(2000);              // wait for two seconds
