I am trying to control a 3-6 volt motor with a raspberry pi and h-bridge. I have a separate power source for my pi and my motors.
I have tried a 6v, 9v, and 12v power source. However, the motor buzzes but will not turn. (The motors turn when power is directly applied).
I am using the code supplied in this link: https://projects.raspberrypi.org/en/projects/physical-computing/16
Is it possible the H-bridge is fried, or is the voltage drop that great? Any suggestion would be great. Also if there is a better way to directly control the motors I am all ears.
