It is a small built-in vibration motor Module. After input 5V current, you can control the ON / OFF or vibration intensity of the motor By digital signal or PWM signal.
This module could modulate your voice on the FM radio wave. And anyone who has a radio device could receive it. We build everything on this module, which makes it very easy to build a tiny radio station
The HW-040 Rotary Encoder Module is a device that generates an electrical signal based on how much the rotary input device (knob) is rotated and the direction it is rotating
