I'm a beginner to stepper motors and Arduino, however I have a project where I need to use both. I need to make the stepper motor rotate 90 degrees with the push of a button, then back -90 degrees when the button is pushed again. I'm very lost and have a deadline so if someone could explain in detail how to go about this I would appreciate it. In addition, I need to wire two electromagnets to the Arduino, and use a different button to turn them on/off. Any help is apprecianted
