 Take the ```/rpi-example``` directory and transfer it to your RPi. You can simply clone this repo on your RPi to get it there easily.  
 Run ```npm install``` in that directory.  This will install the GPIO driver dependencies for the app.  
 Then run ```sudo node unit.js``` to start listening to the UDP packets that will be sent in the next step.
