https://www.electronics-lab.com/project/stepper-motor-based-rotary-encoder-with-clock-and-up-down-direction-signal-output/

This project enables the users to use a stepper motor as a rotary encoder for position control and Up/Down direction control. A bipolar stepper motor can be used as a rotary sensor as it generates two channel strings of pulses by turning the shaft. The circuit provides Step pulse and Up/Down Direction signals by rotating […]

Dual Variable – Reluctance Sensor Interface Module – Stepper Motor Based Incremental Rotary Encoder

This project offers a dual−channel low component count interface solution for ground-referenced variable reluctance sensors. Each of the two identical channels interfaces with a variable−reluctance sensor, and continuously compares the sensor output signal to a user−programmable internal reference. An alternating input signal of appropriate amplitude at IN1 or IN2 will result in a rectangular waveform […]
