Overview

This is a DIY multimedia dial. It rotates like a knob and clicks like a mouse.

 

It works well as an assignable USB controller that you can program to do just about anything you want.

 

 

It’s powered by Adafruit’s Circuit Python so you can quickly program it to run key commands in any application.

 

So you can use it to edit videos, control youtube or even scroll through long documents.

 

Inside the 3D printed knob is a rotary encoder and NeoPixel ring. As you turn the knob, an LED follows the direction making it easy to see where it is.

This uses the Adafruit HID Library for Circuit Python. All of the key codes are listed in the docs so it’s easy to customize your own key commands.

 

It’s powered by Adafruit’s Trinket M0 and runs Circuit Python.
