Digital rotary encoder module

- Operating Voltage: 5V
- Pulse Number for One Circle: 20
- Rotary encoder can count the output pulse times by rotating positively and negatively. This
counting method has no limitation, it can reset and come back to the initial status if matching
with the key on the encoder (that is to say it will count from 0)

-Knob is include

A rotary encoder is a type of position sensor that converts the angular position (rotation) of a knob into an output signal that is used to determine what direction the knob is being rotated.

Due to their robustness and fine digital control; they are used in many applications including robotics, CNC machines and printers.

There are two types of rotary encoder – absolute and incremental. The absolute encoder gives us the exact position of the knob in degrees while the incremental encoder reports how many increments the shaft has moved.
