Funny I came upon this old thread... I am attempting to slow down a small rotating motor for a mobile. I hooked up a potentiometer but it slowed the motor down over a 3º-5º turn. Is there a certain potentiometer to use where I can get at least a 180º turn from 0volt to the 1.5v max? Or if I don't care about varying the speed how do I know what ohm resistor I could put in the circuit to slow the motor down by 25%, 50% or 75%?
