Fun With JavaScript and Sensors
summary
Demos use Firefox OS devices, plain JavaScript and a Node.js server to do real things: a Wi‑Fi hide‑and‑seek that reads SSID signal strength and reliably locates a hidden phone, a theremin from device‑light that maps light sensor values to Web Audio oscillators across multiple phones, a 3JS phone rotation over websockets that streams deviceorientation to render a rotating phone model, and a juggling visualizer shows free‑fall zeros from accelerometer traces that clearly distinguish thrown and caught phones.
