Raspberry Pi with Java 9
summary
Shows Java 9 running on Raspberry Pi 2/3 and using modularity to cut runtime size, with JLink creates small runtime images so apps ship without a full JDK. Demonstrates hardware control via PI4J for GPIO and motors and using PI4J with WiringPi JNI to get microsecond timing for an ultrasonic sensor. Builds a Makeblock line-follower robot follows black tape using PWM motor control and two light sensors that mostly works around a taped track; also sends G-code over USB to a CNC router from Java.
