 ### Key design patterns
 
-**Shared serial port** — `api_layers/port_registry.py` holds a module-level `port_registry` singleton. When multiple devices share one Arduino (e.g. `AnalogInputDevice` + `DigitalIODevice` on the same port), both call `port_registry.get_layer(port, baud)` and get the same `ArduinoLayer` instance. Never construct `ArduinoLayer` directly in device code.

Never construct `ArduinoLayer` directly in device code.
 
-**Device auto-discovery** — `DeviceRegistry._discover()` scans `devices/` with `pkgutil`, imports every module, and registers any class that subclasses `BaseDevice`. Adding a new device type = drop a file in `devices/`, no registration needed.

-**Backend switching at runtime** — `AnalogInputDevice` and `DigitalIODevice` both have `switch_backend(backend, simulate, ...)` that disconnects, reconfigures, and reconnects without restarting. Called from "Apply & Reconnect" in the config dialog.

 ### Arduino firmware
 
-The firmware is embedded as `ARDUINO_FIRMWARE` in `api_layers/arduino_layer.py`. When editing it, set `N_DIG_OUT` to match the number of digital output pins in use (default was 0 — leaving pins in INPUT mode causes inverted write behaviour). Upload via Arduino IDE.

 Serial protocol: `A0:3.14,D2:1\n` stream from Arduino; `W:D7:1\n` / `P:D9:128\n` commands from PC.
