 //----- Simple demo for feeding data to Pachube.
 
 sketch is sending 1 analog and 1 digital sensor readings to Pachube feed: https://pachube.com/feeds/45999
 
 //----- circuit
 
 >>> LED attached to             digitalPin 5.
 >>> button attached to          digitalPin 3.
 >>> analog sensor attached to   analogPin 2.
 
 nanode note: cannot attach anything to digitalPin 8 or digitalPin 9!
