Spacebrew String
2014-04-01 09:35:56 +02:00
2013-08-07 17:16:13 +02:00
Demonstrates how to create a sketch that sends and receives strings
2014-04-01 09:35:56 +02:00
to and from Spacebrew. Every time string data is received it
2013-08-07 17:16:13 +02:00
is output to the Serial monitor.

Make sure that your Yún is connected to the internet for this example
2013-08-07 17:16:13 +02:00
to function properly.
