Hello. I am building an LED striplight for my room. For the device, I would like to have three separate channels so that I can easily color mix Cyan, Magneta, and Yellow. I know the basics of circuitry and wiring the channels, but I am not sure how to control the channels. I was considering using a basic potentiometer or rheostat on each channel and simply dimming each channel by varying the resistance. My concerns with this approach are heating and being able to find a rheostat with a resistance range large enough to give me full intensity control of each channel. Does anyone have a better way of doing resistance dimming? I do theatrical lighting design at a local theatre, and so I am also aware that there are more sophisticated ways of dimming each channel using microcontrollers and such. I believe that this approach would give me much more control over my lighting, but I know almost nothing about making computerized electronics and I would appreciate some advice on the process. Also, I am using CMY mixing because those are the colors we mix for subtractive color mixing in automated dichroic lights at hte theatre. Are different colors used for LEDs? Thank you in advance.
