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);

}

// "TUI" will be flashed in morse code for as long as the device is on.

void loop()

{

// T in morse code

digitalWrite(ledPin, HIGH);   // set the LED on

delay(1000);                  // wait for a second

digitalWrite(ledPin, LOW);    // set the LED off
