There is a connector from the speed controller to the motor.
6 wires from the controller, and 5 from the motor. Red/black go to the front of the motor, other 3
( white blue yellow ) go to the back. People mentioned using a relay, a 2 relay module would have 6 pins, but not sure if a relay would be needed or best. The purpose is to the control the motor using arduino, start/stop the motor at certain time intervals, and maybe change the speed too (but right now I only care about starting and stopping the motor).
Thanks. Hmmm. There could be anything in those 5 cables. Guesses will be uncertain and give You headace.
My suggestion is to use a relay module and just switch the unit on or off.
I suppose number one is using the machine, not use it as a toy for an Arduino project.
