Building Smart Devices using Java on the RaspberryPi-An intro to Pi4J.
summary
Shows Java running on tiny boards (Pi Zero 2 W €15 up to Pi 4 with 8GB) using Pi4J v2 to map the 40 GPIOs into Java objects, with concrete code: context/config builders, LED blink with button-accelerated blink, a buzzer using PWM on pin 18 playing note arrays, and a CrowPi that publishes sensor JSON over MQTT (Mosquitto or HiveMQ) to a JavaFX dashboard built with Tiles. All examples run and are on GitHub.
