/*

  Blink

  Turns on an LED on for one second, then off for one second, repeatedly.

  This example code is in the public domain.

// Pin 13 has an LED connected on most Arduino boards.

// give it a name:

int led = 11;

// the setup routine runs once when you press reset:

void setup() {               

  // initialize the digital pin as an output.

  pinMode(led, OUTPUT);    

}

// the loop routine runs over and over again forever:

void loop() {

  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)

  delay(1000);               // wait for a second

}
