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(200);                  // wait for a bit
 digitalWrite(ledPin, LOW);    // set the LED off
 delay(200);                  // wait for a bit
 digitalWrite(ledPin, HIGH);   // set the LED on
 delay(1000);                  // wait for a second
 digitalWrite(ledPin, LOW);    // set the LED off
 delay(200);                  // wait for a bit
