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.
The author remixed this model.
Removed the sliders for a simple button box.
