Rotary encoder module consists of five pins such as CLK, DT, SW, + and GND. The one we are using is the output rotary encoder and it is the simplest one. There are many types of rotary encoders available which are either classified as the output signal or the sensing technology. Most have 12 steps, but they can be up to 200. On many rotary encoders, when you will move it, you will feel a bump. The rotary encoder has no start, middle, or end, so you can rotate it as much as you want. These can be used to control the brightness of the LED, controlling the servos, and many other things. It generates an analog or digital signal depending on the rotational movement. It determines the amount and the type of rotation.
Introducting Rotary EncodersĪ rotary encoder is such a type of encoder which is used for measuring the angular position of any rotating shaft. Additionally, we will also show you how to control a servo motor through the rotary encoder module. They will focus on how to use the rotary encoder to monitor the direction of rotation. With the help of two sketches, we will show you two different ways to read the rotary encoders. We will discuss about the working of rotary encoders, its pinout, and its connection with Arduino. In this comprehensive user guide, we will learn to interface a rotary encoder module with Arduino.
