Input Output
|
|
|
|
Demonstrates how to create a sketch that sends and receives all standard
|
|
spacebrew data types, and a custom data type. Every time 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.
