Fun with Ruby and Arduino
summary
Claims Ruby can drive real IoT stacks using Arduino and existing gems rather than switching to C++ Python or JS, and demonstrates it end to end. Uses serialport r2 and dino to run LED blink and button demos, a Rails app to toggle LEDs, pubnub for a remote button with ~0.25s round trip, and wit.ai for voice control. Builds working projects: package detector that sends email, streetlight sensor, and an earthquake warning prototype that publishes real‑time readings to freeboard.io and fires alerts (demo peak ≈9.6).
