+  Pachube sensor client with Strings
+ 
+ This sketch connects an analog sensor to Pachube (http://www.pachube.com)
+ using a Wiznet Ethernet shield. 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 String library, which is part of the Arduino core from
+ version 0019.  
+ 
+ Circuit:
+ * Analog sensor attached to analog in 0
+ * Ethernet shield attached to pins 10, 11, 12, 13
+ 
+ created 15 March 2010
+ updated 4 Sep 2010
+ by Tom Igoe
+ 
+ This code is in the public domain.
