12v dc motor control-bi directional with PWM
12v dc motor control-bi directional with PWM
(OP)
Hello
I've just bought a small 12volt gear motor and it seems to work fine in either direction when I swap the wires over. I'd like to use one of the readily available speed controllers on EBAY but not sure whether these will work in both directions simply by changing the polarity?

So I can switch the wires between the controller and the motor but not the wires from the power supply to the controller.
I did see in the description of one controller "reverse polarity protection" which got my alarm bells ringing. I also saw a controller that would switch direction and control speed from the same pot for about £25 which may be a better idea but not sure it has the power capability for my motor
