Node.js & Black Box Prototyping
summary
Prototype of a black box that detects occupancy and pipes events into a web UI using an Arduino ultrasonic sensor wired to a laptop, Node.js reading USB via serialport and publishing through shoe into the browser. Code uses Express, an npm package json-eu-demo and mentions Firmata/Johnny-Five options; a prior demo even rang the audience’s phones via Twilio. Live demo works intermittently—some devices send zeros only—so expect flaky hardware and simple wiring hacks.
