Monsters, lightbulbs and robots: having fun with WebBluetooth
summary
Controls a heart-rate sensor, BLE lightbulbs, a Lego rover and a drone from the browser using navigator.bluetooth.requestDevice and typed arrays; connects gamepad input to the rover with the gamepad API and animates paths with CSS animations. Shows real-world quirks: some bulbs require random bytes or checksums, some only accept writes and cannot be read, Wi‑Fi interference breaks demos, range is ~10–15m, beacons last four years and a physical web puck runs JS and can change lights.
