Installing the lighting controllers

The main lighting controller boards are now ready to be fitted to the Raspbery Pi 2 Zeros and installed under the baseborads.

Each of the four headers will allow 8 pairs of LEDs to operate.

Connecting via 10 way ribbon cable with keyed connectors means as long as you put the connectors on the right way around when you make up the cables you can't get the wrong polarities at the business end.
