This is a 10K ohm linear single turn potentiometer which can be used in conjunction with the Arduino Sun Harvester Shield to switch between different heliostat target groups.
In order to avoid potential issues, either make sure to wire the potentiometer to the shield or disable it by editing the code in the Sun Tracking / Heliostat Program.
Your heliostat(s) will most likely move randomly between target groups if you don't.
Note: The Target Changer Potentiometer is not required if you are only using the shield for sun tracking.
