Component Introduction
A rotary encoder, also called a shaft encoder, is an electro-mechanical device
that converts the angular position or motion of a shaft or axle to an analog
or digital code. There are two main types: absolute and incremental (relative). The output of
absolute encoders indicates the current position of the shaft, working as angle transducers.
The output of incremental encoders provides information about the movement of the shaft.

Result
Rotating the rotary encoder, the stepper motor will rotary in the same direction accordingly.
