I am quite a beginner with this stuff. I have setup a pi to control my garage door through a relay, so that I can open and close it with my smartphone. So I have capabilities of doing things, most times I just need pointed in the right direction. My question now doesn't pertain to the garage door, just wanted to explain that I am not a complete noob.
I am looking for a way to control a stepper motor's rotation through a potentiometer. More specifically I am not looking to control speed but rather the position of rotation. I would like for the potentiometer to be a 1:1 ratio with the stepper motor. (Also am seeking guidance as to whether a stepper or servo would be of better use.)
I understand that an arduino is generally more suited for this use, but I am also seeking a way to eventually have a couple hardware buttons to set points into memory and also to revisit points of rotation through a button press. The ultimate goal is to have a small setup that utilizes a rpi zero to save space (also why I would like to do this without an arduino).
Hopefully this makes sense and I haven't just wasted your time. If anyone has an insight that would be helpful I would be glad to hear it. Thanks in advance!
