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.
