Blink.ino

//
// Blink
//
// The basic Arduino example.  Turns an LED on for one second,
// then off for one second, and so on forever ... or until you
// turn the Duinobot off.
// 
// We use pin 13 as depending on the Arduino board 
// (the Duinobot in our case), it has either:
//    - a built-in LED or,
//    - a built-in resistor so that you only need to add an LED.
//
//  NOTES: 
//      - The Duinobot has an LED so we do not have to add anything.
//      - See http://www.arduino.cc/en/Tutorial/Blink for the original
//        tutorial.

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

void setup()                    // run once, when the sketch starts
{
  pinMode(ledPin, OUTPUT);      // sets the digital pin as output
}


void loop()                     // run over and over again
{
  digitalWrite(ledPin, HIGH);   // sets the LED on
  delay(1000);                  // waits for a second
  digitalWrite(ledPin, LOW);    // sets the LED off
  delay(1000);                  // waits for a second
