Hey everyone, fairly new to the circuit side of things. I teach lighting design at a university and have a soldering project in mind for my students. They will make a circuit to control an RGB led. I have everything sorted out except for the three potentiometers that will each control one color of the led. The problem is, I have no idea how to choose the right resistance of potentiometer. I will have two coin batteries providing 6v. Maybe this is another question for you all because I increase from just 3v because these are the specs I have for the LED's:
Back to my original question, how do I figure out what resistance on a pot I need? I see them at 10k and 20k which I think is pretty common but I don't know if it will do the job I need it to. Any help would be fantastic. Thank you all!
- Forward Voltage:Red:1.9-2.1v Blue/Green:3.0-3.2v(Low Voltage for DIY PCB Circuit);Current:20mA
