Fun with Bluetooth
summary
Browser uses the WebBluetooth API to pair directly with low‑energy devices like heart‑rate straps, lightbulbs and drones; demo connects to a heart monitor and reads live bytes, and writes a 4‑byte RGB characteristic to change a bulb’s color with millisecond updates and CSS-driven animations. Built a self‑driving toy from an SBrick LEGO car controlled by a Nordic Thingy’s accelerometer running JavaScript, flashed a Bluetooth “pumpkin” LED controller, and attempted a drone demo that failed to fly.
