This is the example code used, with my mac and ip info.
/*
Twitter Client with Strings
This sketch connects to Twitter using an Ethernet shield. It parses the XML
returned, and looks for this is a tweet
You can use the Arduino Ethernet shield, or the Adafruit Ethernet shield,
either one will work, as long as it's got a Wiznet Ethernet module on board.
This example uses the DHCP routines in the Ethernet library which is part of the
Arduino core from version 1.0 beta 1
This example uses the String library, which is part of the Arduino core from
version 0019.
Circuit:
- Ethernet shield attached to pins 10, 11, 12, 13
