Newbie question, simple step motor control

Projects General Guidance
1

Hi all,

I'm trying to do something that should be straight forward but I'm getting confused, using a bipolar step motor and a leonardo board, I just want to motor to step through 90 deg intervals, stopping and waiting for an adjustable period of time. the sequence runs over 24 hours i.e. 0 degs for 15 mins, then on to 90 degs for 15 mins etc.

Can't find similar examples that I can re-write withiut getting into trouble.

Any help would be appreciated. Thank you in advance.

You are unlikely to find a sketch that does what you want

  • Can you make the stepper run on command ?
  • Can you make the stepper move through 90 degrees then stop ?
  • Can you make the stepper turn through 90 degrees then stop for a fixed period before doing it again ?
  • How will the stopping period be adjusted ?
  • Do you understand how to use millis() for timing ?
