Blinking LED Breadboard Description

Set up a blink cycle for the Arduino's embedded LED.

Components Used

Arduino Diecmila Board (internal resistor and LED)

Arduino Code

/* Blinking LED
* ---------------------
* Based on Arduino sample code.
*/

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

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

void loop()
{
digitalWrite(ledPin, HIGH); // sets the LED on
delay(5500); // waits for a 5.5 seconds
digitalWrite(ledPin, LOW); // sets the LED off
delay(1500); // waits for a 1.5 seconds
}
