TinyGo: Getting the upper hen
summary
Build uses TinyGo to compile a 29 KB microcontroller binary vs Go's 1.8 MB so it fits a 256 KB Arduino Nano 33 IoT, reads a DHT22 every 10s, and sends HTTP posts to a Kubernetes-hosted Go server scraped by Prometheus and visualised in Grafana. Deployment requires adding a garden access point and powerline cabling for reliable Wi‑Fi; serial logging is handled by a small Go reader; hardware debugging needs an external probe.
