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.
