Detailed introduction:

When you use your computer frequently and need to frequently adjust the volume or want to quickly switch songs in the background, you need a simple and convenient peripheral to assist you. This is this open source project.

Five button states are output through a rotary encoder, namely: left turn (volume -), right turn (volume +), quick press (pause/play), hold + left turn (previous song), hold + right Spin (next song).

And a linear motor is added as a feedback mechanism to give the user a more comfortable experience when rotating.

Main control chip: STM32F103C8T6
