I have a variable color led module. The site says its compatible with RPI, however I can’t find any example code.

AnalogWrite analogWrite analogWrite analogWrite analogWrite analogWrite.The same effect can be achieved on raspberry PI using PWM. I also fine the toptic for you.

int ledPin = 9;    // LED connected to digital pin 9

 

void setup()  {

    // nothing happens in setup

}

 

void loop()  {

    // fade in from min to max in increments of 5 points:

    for(int fadeValue = 0?; fadeValue <= 255; fadeValue +=5) {

        // sets the value (range from 0 to 255):

        analogWrite(ledPin, fadeValue);

        // wait for 30 milliseconds to see the dimming effect

        delay(30);

    }

 

    // fade out from max to min in increments of 5 points:

    for(int fadeValue = 255?; fadeValue >= 0; fadeValue -=5) {

        // sets the value (range from 0 to 255):

        analogWrite(ledPin, fadeValue);

        // wait for 30 milliseconds to see the dimming effect

        delay(30);

    }

I was hoping for python…
