Arduino: Jaws

gistfile1.ino

/*
  Jaws ( aka Blink, but different)
  Start the blinking at interval at 2 seconds. With every successive loop, decrement the intervall by 100ms. 
  Keep looping until you get to 0, then start over at 2 seconds.
 
  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;

// 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:
int i = 2000;                // create a 'crement var
void loop() {
  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(i);              // wait for a 1/4 second
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  delay(i);            // wait for a 1/4 second
  if ( i == 0) {
    i = 1000;
  } else {
    i -= 100;
  }
