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

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 two datastreams, and give them the IDs
sensor1 and sensor2. Or change the code below to match your feed.
This example uses the String library, which is part of the Arduino core from
version 0019.
