I used the following tutorial (https://iotdesignpro.com/projects/raspberry-pi-stepper-motor-control-through-a-webpage-using-flask) to control my NEMA17 stepper motor using a A4988 stepper driver. As soon as I run the stepper.py program I get that error:
Traceback (most recent call last): File "stepper.py", line 4, in from RpiMotorLib import RpiMotorLib ImportError: No module named RpiMotorLib
I have pip 20.2.4 installed.
I'm new to coding so any help is welcome!
