Droids, JavaScript and Web Connected Hardware
summary
JavaScript is used end-to-end: Johnny-Five abstracts motors and sensors, Node handles networking and events, and cheap boards like Arduino ($2–3) run firmware so code talks to hardware. The ecosystem lists about 30 core contributors and 100+ contributors to nodebots. Demos include the classic blink, a Node + WebSocket led toggle from browser to board, an mbot driven remotely over Bluetooth, an LED skirt, large LED panels, and a six‑leg robot solving inverse‑kinematics with Leap Motion in real time.
