I'm trying to figure out what components and the logic I need to understand in order for a rotary encoder to be able to physically control the power output of a capacitor. I know there is a micro controller or processor in the chain of command that the rotary encoder would run through. I imagine that there is some sort of harness that is attached to the PCB which would connect itself to some device that would control the power output of the capacitor. I imagine that its a pretty simple concept, but I haven't found the answer online.
