I am looking to control a 12V 16A 180RPM DC motor. The package I am purchasing includes this motor, and a speed controller. Please see this link for the exact detils.

The speed controller comes with a potentiometer for controlling the speed of the motor rotation.

I have found radio controlled remote controlled switches, like this one, that suits DC motors up to 12V 30A - which would be more than enough for my motor. Button 'A' makes the motor go faster, and button 'B' makes it go slower.

My question is, can a potentiometer (dial or knob like on the wired speed controller) be put into a radio controlled remote like this? And if so, how?

Thanks for any help.

    \$\begingroup\$ Perhaps you hope there's a simple way to connect a remote control receiver to the speed controller you are buying. The ad doesn't mention any suitable input -- the unit seems not designed for that purpose. It may be possible to hack a way to do it, but need a schematic to assess possibilities. You don't want to be inventing from scratch, probably want to leverage existing radio-control PWM control gear if possible. So, question is does this unit facilitate that, or is there an off-the-shelf R/C PWM controller with suitable power handling? \$\endgroup\$

Digital potentiometer may work for you:

Given you want to do some soldering and designing, that is.
