HC-020K Encoder Module Guide

This HC-020K encoder is very useful to sense the motor’s position and velocity. It can be connected to any microcontroller via the 3-pin header. Most HC-020K modules operate with 5V and produce a digital output within the range of 0V to 5V. It will provide a 5V output when the beam is blocked, and a 0V output when the beam is unblocked. Arduino can read the pulse train to determine how far the motor has travelled at what velocity.
