+  Spacebrew Boolean
+ 
+ Demonstrates how to create a sketch that sends and receives a
+ boolean value to and from Spacebrew. Every time the buttton is 
+ pressed (or other digital input component) a spacebrew message 
+ is sent. The sketch also accepts analog range messages from 
+ other Spacebrew apps.
+
+ Make sure that your Yun is connected to the internet for this example 
+ to function properly.
+ 
+ The circuit:
+ - Button connected to Yun, using the Arduino's internal pullup resistor.
+ 
+ created 2013
+ by Julio Terra
+ 
+ This example code is in the public domain.
+ 
+ More information about Spacebrew is available at: 
+ http://spacebrew.cc/
