First time attempting something like this (i work with guitars)
I have an A500K potentiometer, 3x1.5V batteries as power supply, and a vibrating motor from a ps3 controller.
The problem is, motor turns on at about 90% rotation. I want it turning at least before 50%, for a finer control. pot is wired as variable resistor, 3-lug voltage divider wiring method produced the same problem.
I have a range of capacitors and resistors, which i know i could use to somehow make the potentiometer more usefull, just don't know how. most posts about Pot modifications talk about guitar wiring, which is AC and has a ground, but i'm working with DC, and a + and - terminal, which makes things more confusing.
so, my questions are:
What can i do to make the pot more useful?
Does current still pass by the pot at 0 (do i need an on/off switch to save power)?
there has to be a simple sollution.
