FasterLED

/*
  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 = 13;
 int d =1000;

// 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(d);               // wait for a second
 // digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
 // delay(d);               // wait for a second
