  /*
Pachube Data Out

Demonstrates use of the ERxPachube library. 
Push local sensor data to Pachube server.
If you don't have a Pachube account, register one first 
(http://www.pachube.com/).

To run this sketch, you need:
 1. Create a same feed as http://www.pachube.com/feeds/23408
    (A manual feed with three data streams with ids 0, 1, 2.)
 2. Use your API key to replace the space holer PACHUBE_API_KEY below. 
 3. Use your feed id to replace the space holer feed id 23408 below. 

Circuit:
* Ethernet shield attached to pins 10, 11, 12, 13

* Created 22 April 2011
* By Jeffrey Sun
