+
+   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
+   - STM32 Nucleo-144 borads require: STM32duino LwIP and STM32duino STM32Ethernet libraries
