I'm in the process of building an electric honey extractor using a DC motor from a treadmill. I've watched countless videos on wiring up the main board with a POT but my board looks different to the ones in the video and I'm unable to fit the POT directly to the board, model number BC-1068). From my limited understanding I need a PWM but I have no idea how to wire one into the main board to make it work.
The easiest way around this situation would be to buy a speed controller, would the one in the link below work?
