I am trying to figure out how to variably reduce the voltage running to a small DC motor. The motor is powered by a mosfet sending between 0.5v and 3v, so it seems a typical LM317 and potentiometer setup wouldn't work because of the dropout. I'd like to find a way to reduce the voltage by as little as 0.2v, without needing to manipulate the mosfet driver or other parts of the circuitry. Maybe this isn't possible in a simple way.
Obviously I am new to this sort of thing. Thanks for any advice.
