## Overview

The Rpuomtz KY-040 Rotary Encoder Module is a versatile sensor development tool designed for Arduino enthusiasts. This set of 5 modules operates at 5V and features a 20 pulse circuit, allowing for precise counting in both directions. With a reset button for convenience, these encoders are perfect for a variety of electronic projects, making them an essential addition to any maker's toolkit.

## Description

Features:  Material: Electronic components + PCB Size: About 31 * 19 * 29mm / 1.22&quot; * 0.75&quot; * 1.14&quot; Main color: Black Working voltage: 5V Pulse circle: 20  By rotating the rotary encoder can be counted in the positive direction and the reverse direction during rotation of the output pulse frequency, unlike rotary potentiometer count, this rotation counts are not limited. With the buttons on the rotary encoder can be reset to its initial state, that starts counting from 0  How it works: Incremental encoder is a displacement of the rotary pulse signal is converted to a series of digital rotary sensors. These pulses are used to control angular displacement. In Ultra angular displacement encoder conversion using a photoelectric scanning principle. Reading system of alternating light transmitting window and the window is not consisting of radial indexing plate (code wheel) rotating basis, while being an infrared light source vertical irradiation light to the code disk image onto the receiving on the surface. Receiver is covered with a diffraction grating, which has the same code disk window width. The receiver&apos;s job is to feel the rotation of the disc resulting changes, and change the light into corresponding electrical changes. Then the low-level signals up to a higher level, and generates no interference square pulse, which must be processed by electronic circuits. Reading systems typically employ a differential manner, about the same but the phase difference of the two waveforms different by 180&#xA1;&#xE3;compared to the signal in order to improve the quality and stability of the output signal. Reading is then the difference between the two signals formed on the basis,thus eliminating the interference.

    Bad product, missing parts
  

*by T***V on Reviewed in the United States on April 3, 2019*

The labels on the pins are wrong - instead of "A" and "B" outputs, they put CLK and DT. Come on, clock and data on a rotary encoder??? But while this is annoying, I saw that on the product picture and ordered anyway, since it's not affecting the product usability.Why this product got only one stat is because all of the encoders in the package are missing the panel mount screws and washers!
