Controlling electronics with Java and Pi4J is a perfect way to further extend your knowledge and learn about hardware and various communication protocols.

In 2022 articles were published on Foojay.io about using SDKMAN, JBang, Vaadin, Kotlin, and many more on the Raspberry Pi. These prove that Java and the JVM are a perfect match with this small and inexpensive Linux PC for experiments, pet projects, learning, etc.

Let's take a look back at what has been realized in 2022 regarding #JavaOnRaspberryPi and what we can expect in 2023.

An overview of Java projects running on the Raspberry Pi.

In 2021 the Pi4J project released a completely new second version of its object-oriented GPIO API and implementation library for the Raspberry Pi. Let's take a look at the new documentation site and example projects to get you started with Java development on the Raspberry Pi.

Getting started with Java in a new area - like controlling electronic components - can be challenging, but the Pi4J project aims to make this an easy and fun experience. Thanks to a lot of getting-started tutorials and example projects, different use-cases are handled. The experience of your first "blinking LED" is a really amazing experience for a lot of software developers who never interfaced with electronics before. In this presentation, we will take a look at a few of these examples.

Java on the Raspberry Pi is still a controversial topic, but recent evolutions of both the JDK and OpenJFX have proven they are a perfect match! In this talk we will look into some examples and discuss what could be the next steps.

We will take a look at the current state of Java, JavaFX, and Pi4J on the Raspberry Pi. Still, most Java developers didn't consider the Raspberry Pi yet to be the perfect board to run their applications, but with its low price but high specifications, the Raspberry Pi is opening whole new worlds.
