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
