One of the example applications in my book “Getting started with Java on the Raspberry Pi” combines a JavaFX application with Mosquitto on the Raspberry Pi to control a LED strip with an Arduino.

A story of bits, bytes, signed and unsigned Some time ago there was a question on the Pi4J-forum caused by some confusion about a numeric value handled as a byte which was logged as a negative number -86 instead of the expected value 170.

My very first open source JavaFX library is now available in the Maven repository!

And another summer project got finished… ;-) My sons drum corps teacher triggered me to build an Arduino Midi controller so he could practice his rhythm skills.

As a summer project requires, this project required a summer to get completed ;-)

To work out my box-in-a-box I needed two types of materials: something “fluffy” for the walls, and something “strong” to carry the floor.

What do you get if you combine a drum-playing son and a father who doesn’t like to spend thousands of euros?

Great move of Microsoft! They provide an all-in-one installer for Java dependencies and Visual Studio Code.

Some time ago I ordered a “Breadboard Pi Bridge - Pi Ports to Breadboard in Numerical Order” and reworked my Pi test setup from the previous blogs.

What is Pi4J See https://www.pi4j.com/1.2/index.html This project is intended to provide a friendly object-oriented I/O API and implementation libraries for Java Programmers to access the full I/O capabilities of the Raspberry Pi platform.
