This is based on https://github.com/alexchang0229/SatelliteTracker. This was inpired by the SatelliteTracker project (link above). It can track one satellite at a time. CAUTION!!! EXTREME BETA (probably alpha)! Code might not work on some arduinos yet.
USAGE: Simply put the az/el in serial, "az,el". The motors will turn. Make sure to set the full rotation steps value! HELPFUL REFERENCES: https://learn.adafruit.com/adafruit-arduino-lesson-16-stepper-motors/parts
