Blinking LED

Assignment: Introduction to Arduino and Physical Computing

Collaborators:

I modified the code from the example to make the led blink

I modified this code:

 

http://arduino.cc/en/Tutorial/Blink

 

to make the LED blink really fast, close to the threshold of on/off

 

/////////////

 

 /*

   Blink

  

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

  

  The circuit:

  * LED connected from digital pin 13 to ground.

  

  * Note: On most Arduino boards, there is already an LED on the board

  connected to pin 13, so you don't need any extra components for this example.

 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);     

 }

 // the loop() method runs over and over again,

 // as long as the Arduino has power

 void loop()                     

 {

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

   delay(25);                  // wait for a second

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

   delay(25);                  // wait for a second
