Hi,

i have rewritten the code a little bit:

int whiteledPin = 9;  // pin 9 has the white led connected
int blueledPin = 10;  // pin 10 has the blue led connected
int hallPin = 11;    // pin 11 has the hall sensor connected

void setup() {                
  // initialize the pins as output/input and set output to 0
  pinMode(whiteledPin, OUTPUT);
  pinMode(blueledPin, OUTPUT);
  pinMode(hallPin, INPUT);
  analogWrite(whiteledPin,0)
  digitalWrite(blueledPin, LOW);
  
}

// the follow variables are long's because the time, measured in miliseconds,
// will quickly become a bigger number than can be stored in an int.
long time = 0;         // the last time the output pin was toggled
long debounce = 200;   // the debounce time, increase if the output flickers

void loop()
{
  reading = digitalRead(hallPin);

  // if the input just went from LOW and HIGH and we've waited long enough
  // to ignore any noise on the circuit, toggle the output pin and remember
  // the time
  if (reading == HIGH && previous == LOW && millis() - time > debounce) {
    {
      analogWrite(whiteledPin,64);
    }
    if (whiteledPin == 64 && blueledPin == 0)
    {
      analogWrite(ledPinwhite,128);
    }
    if (whiteledPin == 128 && blueledPin == 0)
    {
      analogWrite(ledPinwhite,254);
    }
    if (whiteledPin == 254 && blueledPin == 0)
    {
      analogWrite(whiteledPin,0);
      analogWrite(blueledPin,255);
    }
    if (whiteledPin == 0 && blueledPin == 255)
    {
      analogWrite(blueledPin,0);
    }    

    time = millis();    
  }
    
  previous = reading;
}

but now i see a other problem. when the button is pressed the output will be set to:

  if (reading == HIGH && previous == LOW && millis() - time > debounce) {
    {
      analogWrite(whiteledPin,64);

but the next press will also set it only to:

analogWrite(whiteledPin,64)

right?

other question. is it possible to read out the pwm state of an anlog output like this?

if (whiteledPin == 64 && blueledPin == 0)
