   2  Input Output
   3
   4 Demonstrates how to create a sketch that sends and receives all standard
   5 spacebrew data types, and a custom data type. Every time data is
   6 received it is output to the Serial monitor.

   8 Make sure that your Yún is connected to the internet for this example
   9 to function properly.
