In the previous video we wrote code to read out the pulses and the switch of a rotary encoder. We are now going to use this to tune a servo motor.
With every mechanical construction where a servo is used to move something (garage doors, a gate beam, a turnout), the minimum and maximum servo angles need to be found for the construction to operate like we want it to. In this video we are going to build a 'servo tuner' to find those angles.
