+ Spacebrew String
+
+ Demonstrates how to create a sketch that sends and receives strings
+ to and from Spacebrew. Every time string data is received it
+ is output to the Serial monitor.
+
+ Make sure that your Yun is connected to the internet for this example
+ to function properly.
+
+ The circuit:
+ - No circuit required
+
+ created 2013
+ by Julio Terra
+
+ This example code is in the public domain.
+
+ More information about Spacebrew is available at:
+ http://spacebrew.cc/
