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(500);                  // waits for a half second
digitalWrite(ledPin, LOW);    // sets the LED off
delay(500);                  // waits for a half second
