The hardware

The idea was that by making voltage dividers for every input plug we would be able to identify which input plugs are connected on the arduino.

Below you see the first prototype on a breadboard with some voltage dividers, here we found that when you connect two of the circuits the resistance (or rather, the voltage) of these two would become the same. This is how we tell the arduino that two plugs are connected.

Then we made a panel with jack inputs and connected it to the breadboard to see if this would still hold up.

We can see on the computer that when no cables are connected we get six different numbers, as soon as we make a connection the numbers of the corresponding jack inputs become the same.

Then we made the top panel for the box from semi transparent perspex, we expanded to sixteen voltage dividers, using different resistors for every input.

We made a system with magnets to seal the top panel to the box, we soldered the circuit and mounted everything in the box. You can shake the box or hold it upside down and it won't break. We wanted to make it as durable as possible.
