Wiring the Internet of Things with Node-RED
summary
A live demo shows Node-RED running in a browser on a Raspberry Pi with Sense HAT, reading motion and joystick input, throttling events, and driving the 8x8 LED display; a BLE puck.js button toggles colors via messages routed through a Watson IoT QuickStart node. Project features add git-backed versioning and the flow is pushed to devices via resin.io so the same Docker image deploys to other Pis. Project stats cited: ~1,660 third-party nodes and 1,000,000+ NPM installs, and the demos mostly work end-to-end.
