"IoT Prototyping with Firebase and JavaScript"

on YouTube ↗42m

" summary

A concrete one-off IoT recipe: use Arduino Uno with Firmata + a breadboarded LED on pin 13 and a button on pin 2 with a 10K pull-down resistor, drive it from Johnny-Five + Node.js on a laptop or Pi, and mirror state to a Firebase realtime database URL. The demo wires, copies/pastes the Johnny-Five snippets, sets ref.set('down'/'up') on button events, and the LED and Firebase dashboard update in real time — the prototype works as shown.
