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 bit
digitalWrite(ledPin, LOW); // set the LED off
delay(1000); // wait for a bit
digitalWrite(ledPin, HIGH); // set the LED on
delay(500); // wait for a second
digitalWrite(ledPin, LOW); // set the LED off
delay(400); // wait for a bit
