A project demo showing how to control an Arduino-driven LED strip wirelessly using a JavaFX application and Mosquitto message queue running on a Raspberry Pi. The setup includes a color picker UI, a command log table, and a web interface served via Undertow. Commands are exchanged between all components through the Mosquitto queue, keeping them decoupled. Source code for both the Java and Arduino sides is available on GitHub, and the full walkthrough is covered in the book 'Getting Started with Java on the Raspberry Pi'.
