How can I add wireless functionality to a simple electric motor? (lemmy.ca)

I have one of those basic motor kits you can buy off of Amazon. I was wondering what steps I should take to make it so that I can turn the motor on/off with the press of a button, wirelessly.

I'm still very new, so any information you can offer no matter how basic will probably be useful to me.

IANAEE. For an on-board application you can create a simple switch with a transistor. https://www.electronics-tutorials.ws/transistor/tran_4.html

To make something wireless you'll probably want to go with a microcontroller or Raspberry Pi and hook up GPIO pins to the motor controls. A transistor wouldn't be needed in that case as the microcontroller can hold the pin high or low depending on what state you want.
