Hi, all. I would like to power a small low speed DC stall motor (12V max) using an analog joystick. It would be easy, I think, if the joystick were max or min at center, then variable in either direction. However, the joystick I have is 10K ohms with 5K at center rest. It lowers resistance when shifted down and the reverse when shifted up.
Does anyone have a circuit that would do this? I realize I could simply use a DPDT to switch polarity, but that would not supply variable speed. I want to keep it simple, not using Arduino, etc.
I'm not very electronically literate. I can use passive components ok, but have little experience w/ chips, transistors and the like.
Thank you
Duke
