Hello again. Maybe I explain evil. The engine should always have a "home" position. Whenever the switch is open (low) should be in that position or return to it if the engine has moved. Instead, pressing the switch (high) should always go to a certain position (1000 steps for example). Thanks again.
Sorry, no programming know, I'm not an engineer or student, just that I like electronics. I have no job and this is for a small job of a model they have asked me so I need your help. Thank you.
