Having fun with Java and JavaFX on the Raspberry Pi

on YouTube ↗36m

" summary

A working prototype ties a Raspberry Pi 4 plus 7" touchscreen to a relay board and an Arduino‑driven RGB LED strip, uses JavaFX touchscreen UI built on Java 11 (BellSoft Liberica or Gluon) and pi4j/py4j for GPIO, runs Mosquitto as an MQTT broker to route commands from a web page and a JavaFX app to the Arduino, shows distance‑sensor charts and LED effects (demoed at ~60 fps), and successfully toggles mains relays and remote alerts.
