+  Wifi Pachube sensor client with Strings
+ 
+ This sketch connects an analog sensor to Pachube (http://www.pachube.com)
+ using a Arduino Wifi shield.
+ 
+ This example is written for a network using WPA encryption. For 
+ WEP or WPA, change the Wifi.begin() call accordingly.
+ 
+ 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.
+ 
+ This example uses the String library, which is part of the Arduino core from
+ version 0019.  
+ 
+ Circuit:
+ * Analog sensor attached to analog in 0
+ * Wifi shield attached to pins 10, 11, 12, 13
+
