Nexus sensor integrated.

I managed to integrate the Nexus sensor into the system - this meant simply re-loading code. The problem with this was that people kept stopping and asking me what I was doing ( I did have the floor up). 

I spent ages trying to get the think working and kept getting connection not accepted. Eventually I discovered the code had the wrong port. 

Finally I found I didn't reboot sleepless so the laptop fell asleep. 

Tommorow I'm going to replace the sunspot with a clone of the ardiuno sensor + move the second pad. 

Need to get a good process running for the update visualisation.
