Stepper motor doesn't move, only vibrates
I've been using the Adafruit stepper motor tutorial for RPi and have been unable to to get the motor to turn. The motor will only vibrate and buzz every time i run the python script. I'm using the L293D motor driver and 28BYJ-48 step motor. Wiring has been checked and rechecked countless times. dc motor works fine, as well as servo's but following the instructions exactly nothing happens. Any insight would be greatly appreciated.
