## Overview

The Tegg KY-040 Rotary Encoder Module offers 360-degree continuous rotation with 20 pulses per revolution, powered by a stable 5V supply. Featuring a built-in clickable switch and a durable aluminium knob, this compact sensor is ideal for Arduino projects requiring precise input control, menu navigation, or motor control. Sold as a 2-pack, it delivers excellent value for makers and professionals alike.

## Description

Description: Type: KY-040 Rotary Decoder Encoder. Operating Voltage: 5V. One round number of pulse: 20. Width: 19mm/0.75 Inches. Length: 30mm/ 1.18 Inches. Height: 28mm/1.10 Inches. Material of Knob Cap: Aluminium Alloy. Diameter of Knob Cap: 14mm/ 0.55 Inches. Height of Knob Cap: 17mm/ 0.67Inches. Package:2 PCS. Pin description: CLK - equivalent to output A in regular encoder. DT - equivalent to output B in regular encoder. GND - equivalent to output C in regular encoder. SW - reset switch. + (VCC) - positive supply to the unit. The KY-040 rotary encoder is a 360 degree rotary input device (i.e. a control knob) that provides an indication of how much the knob has been rotated AND which direction it is rotating in. It is a great device for stepper and servo motor control. You can also use it to control devices like digital potentiometers. It is ideal for navigating menus on a display or taking inputs such as numbers or text characters. The range of input can be easily defined and mapped in software. A push button switch is built into this encoder. If you push on the shaft, the normally open switch "SW" will close. This can be used as an On/Off switch, to change control functions, ranges, selecting a menu item or entering a number. The "D" shaft of the encoder can be fitted with a knob for using it in a product.

Review: Great value! - Worked as expected. Great value!
Review: Solid and Basic - This was for an Arduino project, works as advertised. Not heavy duty but I didn't need that. The knob is a little cheap feeling, a little sharp in the knurls. I might take an emory board to it or just use another knob. Would probably buy it again. I didn't need 5 so these two are fine.

noisy readings - can be solved with adding "delay(10)" and "no interrupts" command within the interrupt used.
