I don't get it. Node.js is for fast, scalable servers that are IO bound. Arduino is for low-level hobby projects like blinking lights and moving motors. They can be part of a larger network of devices, but that's not the point.<p>My first Arduino project was a TCP server that turned a servo depending on a JSON request (it kinda followed the websocket protocol, without the handshaking). The client was a simple Go app. I understand the possibility for networked Arduino devices, but I think this project misses the point of Arduino development.<p>Not everything has to be written in JavaScript. The Arduino team has made C++ approachable for beginners, so develop for the Arduino, and you'll learn a lot more.
