Hey, my names brandon and im working on this project but i seemed to have run into a problem. Im trying to make a circuit to switch polarity multiple times a second. i want a motor to switch from positive to negitave and be able to control how many times a second it switches polarity. and also if possible i would like to be able to control the voltage as well. The project is not real big so i wouldnt want my circuit to be real big. Im not sure if this circuit would be possible but i hope someone could help me. I called a electrician and he told me i was crazy. Please help me. does anyone think that it could be done?
