KY-040 Rotary encoder module brick sensor for development board 360 degree

A 360-degree Rotary encoder is a Bread board-friendly extremely precise module that provides an indication of how much the knob has been rotated and what direction it is rotating in. It is an incremental electro-mechanical device that converts the angular position or motion of a shaft or axle to digital code. The output of incremental encoders provides information about the motion of the shaft, which is typically further processed in processor/controllers into information such as speed, distance, and position.
