DIY Rotator Controller

By Anthony Guiller E. Urbano, DU1AU
February 2020

I have just finished building a DIY controller as part of a home-brewed antenna rotator project. The controller allows simple clockwise and counterclockwise movement of the stepper motor using 4 buttons. The motor may be replaced with a larger one depending on the intended load. I have added an optional speaker for audible feedback.

To view the circuit diagram, head directly to Stepper Motor Controller using Arduino.
