int led = 3;          

int brightness = 0;    

int fadeAmount = 5;    

void setup() {

  pinMode(led, OUTPUT);

}

void loop() {

  // set the brightness of pin 9:

  analogWrite(led, brightness);

  // change the brightness for next time through the loop:

  brightness = brightness + fadeAmount;

  // reverse the direction of the fading at the ends of the fade:

  if (brightness <= 0 || brightness >= 255) {

    fadeAmount = -fadeAmount;

  }

  // wait for 30 milliseconds to see the dimming effect

  delay(1);

}
