import br.com.criativasoft.opendevice.core.SimpleDeviceManager;
import br.com.criativasoft.opendevice.core.connection.Connections;
import br.com.criativasoft.opendevice.core.model.Device;
import br.com.criativasoft.opendevice.core.model.DeviceType;

public class Demo extends SimpleDeviceManager {
    public static void main(String[] args) throws Exception {
        new Demo();
    }
    public Demo() throws Exception {
        Device led = new Device(1, DeviceType.DIGITAL);
        // setup connection with arduino/hardware
        addOutput(Connections.out.usb()); // Connect to first USB port available

        connect();
        addDevice(led);
        while(true){
            led.on();
            delay(200);
            led.off();
            delay(200);
        }
    }
}

Now you must see the LED blinking in the Arduino

Tip
Of course you can use the "SimpleDeviceManager" without using inheritance only calling instance.

Other usage style, it's working directly with the connection.
It is more decoupled, but less powerful
