led-bridge: add ESP32 indicator firmware for reference#17
Merged
Conversation
Stores the Arduino sketch that runs on the ESP32 LED indicator alongside
the host-side led-bridge.go that drives it. Reference only — not built or
flashed by this repo. Header documents the wiring and the {"state":"..."}
serial protocol the firmware matches against.

What
Adds the Arduino sketch that runs on the ESP32 LED indicator as a reference file at
resources/led-bridge/firmware/led-indicator.ino.Why
led-bridge.gois the host-side half that drives the indicator over USB serial; this is the firmware half that receives those updates and renders the LEDs. Keeping both in the repo makes the serial contract reviewable in one place.Notes
.inoso GitHub highlights it and it opens directly in the Arduino IDE.{"state":"..."}serial protocol the firmware substring-matches against (mirrorsactionForStateinled-bridge.go).🤖 Generated with Claude Code
