USB Volume control

Arduino Uno - USB Volume control
===========================

This is my version of a huge USB Volume controlknob.

Parts needed:
* 1x 12mm rotary encoder + switch - https://tinyurl.com/y7u6m3on
* 1x Arduino Uno - https://tinyurl.com/ycbbuyzx
* 1x NeoPixel Ring 12 leds - https://tinyurl.com/yboseqnl
* 3x m3x10 screw
* Some jumper cables - https://tinyurl.com/ycqqhkb3
* The arduino sketch - https://tinyurl.com/yatn9xko

**All parts print without support.**

Once you downloaded the source you will notice that this actually has two sketches.
This is because we also use the atmega 16u2 on the Uno-Board.
**This is why you will need an original Arduino/Genuino**
Clones often use a different chip for usb-connection.
The atmega 328p will poll the rotary encoder and control the neopixel leds.
The atmega 16u2 will fake a USB-HID device and send the volume-control-commands.
