By the end of the week the Adafruit Motor HAT will be in my local store. I'll ask for a 12V stepper motor and try to get that to work. Then I will begin with step two: putting it on my telescope. I have a Starway Crayford Focusser with a 10:1 micro focussing. A canon 700D will be attached to it.
This will be my second electronic DIY project after putting the raspberry PI together. So I'm a newbie on this topic
