TinyGo: Getting The Upper Henn
summary
Project uses Arduino Nano 33 IoT and a DHT-22 sensor with TinyGo to sample temperature and humidity, compile small binaries (hello world drops from 1.8 MB to ~107 KB) and flash OTA via tinygo flash. Readings POST every 10s over Wi‑Fi to a home Kubernetes web server scraped by Prometheus and displayed in Grafana; live demo shows humidity spike to ~91.5%. Hardware works but needs a garden router for range; plan is to switch HTTP to MQTT and remove the long cable.
