USB Volume control

Arduino Uno - USB Volume Control =========================== This is my version of a massive USB volume control knob. 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 download the source, you will notice that this actually has two sketches. This is because we also use the atmega 16u2 on the Uno board. **You will need an original Arduino/Genuino to make it work.** 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 volume-control commands. https://www.youtube.com/watch?v=XHZvN9ZqyF4 https://www.youtube.com/watch?v=ZvOYcb3yuW4
