Does anyone know how to drive a stepper motor without a stepper motor driver?(Strait from the Arduino maybe?)
You can use ordinary switches or relays, but not an Arduino. To take step, change which coil is energized.
Some power transistors or a H-Bridge would work, but it’s probably easiest to use a stepper motor driver IC to do the heavy lifting for you. That would greatly simplify your circuit and code.
Ok. Thanks!
