Turret Rotation Sensor

[EricWilliams]

Absolute encoders can be a lot nicer than continuous pots, but a cheaper solution is to just have your turret turn towards a limit switch at the beginning of the math, and zero your encoder when it hits the switch.

This is a nice approach because if there is slip between the sensor and turret, the limit switch will correct for it.

Also, a lot of the advantages of absolute position-sensing sensors are lost once you have a reduction between the turret and the sensor (unless you have a multi-turn pot).
