How to control a RGB LED with a button or knob? Answered
I would like to create an led powered by batteries that can change from Green to Yellow to Red and off.
I can use either one RGB led or 3 different leds (Reg, green and yellow obviously)
If having a yellow light makes this more challenging, then I can change the yellow to blue.
Do I need a controller? Can I just use wires and resisters? I would like to keep this as simple as possible to start out.
The whole idea is to have someone be able to either turn a 4-position knob, or push a button to change the color of the LED.
I saw another question on Instructables about this topic, but I could not find any solid answers.
Thank you for any help you can provide. If you need me to provide more information just ask. Thanks again.
