In this talk, we'll look at the current state of Pi4J along with some examples, like blinking an LED, sending sensor data to a message broker, running a Spring application, and playing an FXGL (JavaFX gaming engine) game.

We'll experiment with Java on a CrowPi to read values from sensors and control other electronic components.We will be using IntelliJ IDEA to write the code, push it to the Raspberry Pi to run the application, and interact with hardware components like an LCD display, LED matrix, buzzer, and so on.
