##Xively WiFi Sensor Tutorial##
This sketch is designed to take sensors (from photocell) and upload the values to Xively
at consistant intervals. At the same time it gets a setable value from Xively to adjust the brigthness
of an LED. This sketch is reusable and can be adapted for use with many different sensors.
