Hi !!
Amazing! 
The code you writed works perfect !!
The stepper im using for testing now is only 200steps/revolution so i changed that to get it runnning.
I tried to add an if statment to the button (shortpress) and it works to print out "return to refrencepoint" But im not able to get the stepper to return to Refrencepoint. I tried using the
stepper1.stepsToDo();
but nothing happend,
The thing i want to happen when the button is pressed short is to get the motor return to refrencepoint.
When i get the compass sensor running i will read out an angle, when i press the button twice i want the stepper to move hold the angle set when pushing twice on the button. What function is best to use for this task? If button pressed twice set compass refrence point, if compas direction change the stepper should move the same amount of rotation.
Once again Thank you som much for helping me with this !
Best Regards
Andreas
