int durations[] = {400, 400, 400, 1000, 1000, 1000, 400, 400, 400};



void setup()                    // run once, when the sketch starts

{

  pinMode(ledPin, OUTPUT);      // sets the digital pin as output

}



void loop()                     // run over and over again

{

  for (int j = 0; j < 9; j++)

  {

    flash(durations[j]);

  }

  delay(6000);                  // wait 1 second before we start again

}



void flash(int duration)

{

  digitalWrite(ledPin, 1);

  delay(duration);           

  digitalWrite(ledPin, 0);    

  delay(duration);

}
