Mac Mini without Shell

We connected the blue wires to the Mac Mini’s power switch in order to power the Mac on and off with an Arduino. Using this Arduino, we wanted to enable switching the whole TwinTable system (Projector, Mac, Lighting, Ventilation) on and off with a switch mounted to the TwinTable’s body. However, we eventually decided to only switch on and off the projector and let the Mac, the lighting and the ventilation run all of the time.
