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.
