PWM BASED LIGHT WAVES USING MSP430G2553 FOR CHRISTMAS CRIB



PROGRAM

int led = 10;           // the pin that the LED is attached to
int brightness = 0;    // how bright the LED is
int fadeAmount = 5;    // how many points to fade the LED by
int brightness2 = 0;
// the setup routine runs once when you press reset:
void setup() {
  // declare pin 9 to be an output:
  pinMode(led, OUTPUT);  pinMode(11, OUTPUT);
}

// the loop routine runs over and over again forever:
void loop() {
  // set the brightness of pin 9:
  analogWrite(P1_2, brightness);
    brightness2=  255-brightness;
analogWrite(P2_1, brightness2);
  brightness = brightness + fadeAmount;
  brightness2=  255-brightness;
  // 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(6);
