Description

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

Components

Blue Light Emitting Diode (LED)

220 ohm resistor.

Code

/*
Modified Blink

Turns on an LED on for 1/10th second, then off for 1/10th second, repeatedly.

The circuit:
* LED connected from digital pin 13 to ground.

based on an orginal by H. Barragan for the Wiring i/o board

*/

int ledPin =  13;    // LED connected to digital pin 13

// The setup() method runs once, when the sketch starts

void setup()   {                
// initialize the digital pin as an output:
pinMode(ledPin, OUTPUT);     
}

// the loop() method runs over and over again,
// as long as the Arduino has power

void loop()                     
{
digitalWrite(ledPin, HIGH);   // set the LED on
delay(100);                  // wait for 1/10th second
digitalWrite(ledPin, LOW);    // set the LED off
delay(100);                  // wait for 1/10th second
}
