Getting started with microcontrollers and Google Cloud IoT Core
summary
An affordable Arduino-compatible MCU is flashed over USB to read temperature and humidity sensors, the sketch uses Arduino libraries and is uploaded during the demo, and telemetry is sent to Google Cloud IoT Core via MQTT/HTTP. Device registration uses JWT asymmetric auth and public keys, messages land in Cloud Pub/Sub and are visualized as realtime time‑series charts. The demo runs end‑to‑end on stage, shows a working sensor pipeline, and notes Cloud IoT Core can handle many devices (demo uses a small fleet).
