  the Adafruit Ethernet shield, either one will work, as long as it's got
  a Wiznet Ethernet module on board.
  
+ This example has been updated to use version 2.0 of the Pachube.com API. 
+ To make it work, create a feed with a datastream, and give it the ID
+ sensor1. Or change the code below to match your feed.
+ 
+ 
  Circuit:
  * Analog sensor attached to analog in 0
  * Ethernet shield attached to pins 10, 11, 12, 13
