|
Adapt the Blink example (https://www.arduino.cc/en/tutorial/blink) as a
|
|
simple MQTT prop. Avoid delay() calls (except short ones) in loop() to
|
|
ensure CPU for MQTT protocol. Use PropAction checks instead.
|
|
|
|
Copy and change it to build your first Arduino connected prop, you will
|
|
only be limited by your imagination.
|
|
|
|
Requirements:
|
|
- install ArduinoProps.zip library and dependencies (https://github.com/fauresystems/ArduinoProps)
|
|
- help: https://github.com/xcape-io/ArduinoProps/blob/master/help/ArduinoProps_sketch.md
