Topic: Softpot Rotary Potentiometer to change the color of your LED's (Read 43 times) previous topic - next topic


Hello there,

I have bought a Softpot Rotary Potentiometer of SpectraSymbol, that I want to use for changing the color of the LEDs I'm using for my graduation project. I'm really bad in coding so I wanted to ask your for help. You would be my hero of the day! :smiley-wink:

This code,  comes from http://bildr.org/ but when you let go the sensor it goes back to it's original resistance. The thing I need, is that when you touch it, it will stay at that number of resistance so this can be linked to the RGB code, so you can actually choose your color.

int softpotPin = A0; //analog pin 0

void setup(){
  digitalWrite(softpotPin, HIGH); //enable pullup resistor

void loop(){
  int softpotReading = analogRead(softpotPin);

So first: How can it stay at the same resistance code?
Second: How does the code look like when a resistance number is linked to a specific RGB color.

(one example will do, just to get the idea)

I really hope somebody can help me out.
Thank you very much in advance!
