Hey, guys!

I need a remotely (Bluetooth) controlled stepper motor. It has got to be SUPER tiny (hence PICO).
Does anyone know if PICO could be used to control a stepper motor via Bluetooth (HC-05)?

Thanks ahead!

Going to take a guess that it most likely won't. If the current draw of the motor is low enough it would be possible to use just the pico I would think. Otherwise you'll need some circuit between the pico and the motor. Most times an off the shelf stepper controller can be used pretty easily.
