The Board
The Arduino now needs the inputs, outputs, power connections and grounds attaching.

The wiring diagrams are in the images below of the whole wiring set-up and also one of the stripboards, and the photos have notes on them to show how this corresponds with the actual board.

We are using 3 analogue inputs from the pots and 6 digital outputs to the stripboards, with pulse width modulation (pwm). There are 3 grounds coming back to the board from the 3 stripboards.

There is 3v power from one supply to the 3 stripbaords, and 7.5v power to the arduino board from another power supply.
