Final

This final LightShare code is based on Pachuino. It runs on the new Standard_Firmata, ver 2.1, code in Arduino 18. You must import 'pachuino', 'serial' and 'arduino' libraries into your processing sketchbook. The reason that we are able to use this code on pachube.com is the fact that we got whitelisted for the duration of the assignment. This meant that the data cap was removed. It is set up to listen for 1 set of local sensor data and 3 remote sensor feeds;

Using this code meant that we could separate the data coming from each persons feed, to deal with them separately in the if and else statements.

Below is the fritzing diagram of the circuit and an image of the finished switch box. In the final we used a Potpin instead of a toggle switch just to save a bit of cash. Worked nicely.
