I was wanting just a simple MisteRdeck for running a few hotkeys, I don't have a need for sliders, so I removed them.

I left space for adding a logo on the front.

This version uses the Micro USB board (as those are the ones we had).

As my MisteRdeck isn't using MIDI, I used the DeeJ.ino file, so the Arduino connects over USB as a keyboard.  Without changing the file, each button press will simulate the key press combination  [SHIFT] + [CRTL] + [ATL] + F1   through to  [SHIFT] + [CRTL] + [ATL] + F12.

I use Linux Mint, so to define the key board shortcuts I used the ‘Keyboard’ application and under ‘shortcuts’, got to defining application launchers and system actions.
