/*
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/26318
 (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 PACHUBE_FEED_ID below. 
 
 Circuit:
 * Ethernet shield attached to pins 10, 11, 12, 13
 
 * Created 22 April 2011
 * By Jeffrey Sun
 * http://code.google.com/p/pachubelibrary/
