Introduction to Pi4J (Java on Raspberry Pi)
Tuesday, January 14th, 2025: 11:30 AM to 1:00 PM
Java is not only the server language running on heavy machines! You can do amazing stuff with it on a small single-board computer and gain new knowledge simultaneously, like controlling electronic components and different communication protocols.

A Raspberry Pi is a complete Linux PC with a small form factor with a low price. And, of course, you can run Java on it. The same kind of JVM applications you know, love, and use on heavy machines can also be used on the Raspberry Pi. "Write once, run everywhere"?
Ah yes, that's Java's promise! But this small board has some additional possibilities you will not find on that fancy server you are running somewhere in the cloud. All Raspberry Pis have those 40 magical pins to connect unlimited electronic components. Measuring temperatures and distances, toggling LEDs and relays, controlling the content on an LED matrix or LCD display, playing the Star Wars tune on a buzzer... the only limit is your imagination!
In this talk, we'll look at the current state of Pi4J (www.pi4j.com) and dive into the code of a few examples. We'll experiment with Java on a CrowPi - a Raspberry Pi-based laptop to interact with electronic components.
