Builds a JavaFX touchscreen UI on a Raspberry Pi that drives a relay board (220 V switches) and an Arduino‑connected LED strip over Wi‑Fi, using Pi4J for GPIO, Mosquitto MQTT hub for messaging and Undertow/Spring for a tiny web server. Shows a 7" touch control, LED effects selectable from a web page and JavaFX app, distance sensor and button input graphed live, and confirms messages arrive and LEDs change color — examples and code collected in an ebook.
