questions for #electronics builders from a noob:

I want to build a weird lamp composed of sub-lamps with a slider pot to control the brightness of each one via a microcontroller watching the pot on an ADC pin and doing PWM.

* what resistance range is good for this such that the slider will have an effect over its full range of travel?

* slider pots tend to have a huge tolerance of like 20%, is this usually fixed by testing each one and adding fudge factors to the code?

any #electronics tinkerers out there got a standlight circuit for a 3 watt bike dynamo?

I'm about to drag my bike out of storage, currently it has the dynamo and incandescent lights (2.4W front, 0.6W rear).

I have almost no experience and can barely solder, fwiw. #LearnElectronics
