I have a Raspberry Pi 3 with the corresponding power supply and I'm looking for a motor that can be used without battery or external motor. The final goal would be to activate a motor in both directions (in order to act on a wall switch1).
For example, can a motor be powered by an USB port and controlled with the USB link or GPIO? It would ease connections.
Please share names or references of these motors if they exist.
(1 I know that I can replace the wall switch with a electric relay but I'm not considering this solution at the moment)
