and is controlled using the included Arduino’s Servo Library. The code is simple too and I’ll try to explain it after this video where I made a short presentation of the project in action.

A servo uses a potentiometer attached to the output shaft in order to sense position, and the internal electronics take care of driving the motor to move the shaft to the desired angle.

However, in the place of a potentiometer, this design instead uses an AS5600 magnetic rotary position sensor to read the servo’s angle, via a magnet mounted in the servo’s gear. An Arduino is ...
