Fake Logitech MX Dial

Did not want to spend the cash on the current trendy creative consoles?
Have a spare SAMD21, 360° clicky potentiometer , 4 x buttons, 4 x 10k ohm , and some wire.

the 3d printed shell also is really handy, also the code.
thanks to HunterK55
while this could be a simple project, not having to start code from scratch made this a million times better.

Have fun and remember to turn off the soldering iron.
Also Don't load the code 5 times back to back......it doesn't like that.
