Hardware 2.0 is upon us: cheap micro-controller boards like Arduino have gained massive adoption in recent years. Paired with 3D printers, cheap sensors and actuators, it allows anyone to prototype the next hot gadget. And yet, the maker will have to learn a soup of software language and framework to build a connected IoC solution: C++ for the micro-controller code, HTML + javascript for the client, some backend language and a communication layer to interact with the devices. In this session, we will show an attempt at unifying the compilation of web server code, rich client and embedded firmware under a simple mobile friendly language and IDE.
