Abstract: This paper presents a precision capacitive rotary encoder that integrates a shared charge amplifier, and a multi-stage offset calibration scheme. Recently, capacitive encoders have gained ...

This project implements an encoder-based measurement system and PID control for motor speed using Arduino. It includes pulse reading, speed calculation, and closed-loop PID control with simulation ...
