Last year we started a new Internet of Things project: The Internet of (Lego) Trains. In our normal jobs we use languages like Java and Scala to build applications for large organizations. We wanted to find out if we could use the same languages and tools on IoT hardware. We also wanted to investigate whether or not (remote) actors could replace REST endpoints in our applications. Next to that it was also a good excuse to play with Lego. The Lego trains are equipped with a Raspberry Pi, camera, wireless dongle, infrared transmitter, speaker, RFID reader and battery pack. Next to that we have automated switch tracks and camera’s again with the help of Raspberry Pi’s. We also build some lightning effects with LEDs controlled by Particle Photon’s. On top of that we also automated a Lego ferris wheel. To control the trains and other parts we built an remote actor based application with Scala, Akka, Akka HTTP and AngularJS. In this session we will talk about our experiences and challenges and of course we will give a live demo!
