" summary

Demonstrates concrete device work: using web Bluetooth (BLE GATT services and characteristics, notifications, Eddystone/Physical Web) to control a lamp, read heart rate and temperature — works in Chrome on Android, spotty on Windows; requires HTTPS and a user gesture. Shows web USB powering and programming a device over cable (claim: live JS upload and run), available behind flags/origin trials. Adds NFC tag read/write, a barcode detector API, and Generic Sensor API for Daydream controller demos; Linux modem-manager and driver quirks noted.
