- Wifi Twitter Client with Strings
-
- This sketch connects to Twitter using using an Arduino WiFi shield.
- It parses the XML returned, and looks for <text>this is a tweet</text>
-
- This example is written for a network using WPA encryption. For
- WEP or WPA, change the Wifi.begin() call accordingly.
-
- This example uses the String library, which is part of the Arduino core from
- version 0019.
-
- Circuit:
- * WiFi shield attached to pins 10, 11, 12, 13
-
- created 23 apr 2012
- modified 31 May 2012
- by Tom Igoe
-
- This code is in the public domain.
