 Turns on an LED on for one second, then off for one second, repeatedly.
 The circuit:
 * LED connected from digital pin 13 to ground.
 * Note: On most Arduino boards, there is already an LED on the board
 connected to pin 13, so you don't need any extra components for this example.

 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(1000);                  // wait for a second
  digitalWrite(ledPin, LOW);    // set the LED off
  delay(1000);                  // wait for a second
