+# Arduino Info Display
+
+Small info display project for an Arduino MKR1000 with:
+
+- SH1106 OLED display
+- AM2302 temperature and humidity sensor
+- Two control buttons
+
+The device is intended to show a compact set of useful screens, navigated with:
+
+- `Select` button
+- `Next` button
+
+## Planned Screens
+
+The display should support at least these views:
+
+- Local time
+- Weather forecast
+- Temperature from the AM2302 sensor
+- Humidity from the AM2302 sensor
+
+Additional screens can be added later once the basic navigation and data sources are in place.
+
+## Project Status
+
+This repository is currently in the documentation and planning stage.
+
+- PlatformIO project initialized
+- Target board configured as `mkr1000USB`
+- Initial hardware wiring notes documented
+- Application code not started yet
+
+## Repository Layout
+
+- [`platformio.ini`](platformio.ini): PlatformIO configuration
+- [`src/main.cpp`](src/main.cpp): Placeholder application entry point
+- [`docs/project-overview.md`](docs/project-overview.md): Functional scope and behavior
+- [`docs/hardware-notes.md`](docs/hardware-notes.md): Component and wiring notes
+
+## Initial Goals
+
+- Build a stable display loop for multiple screens
+- Support simple button-based navigation
+- Read local temperature and humidity from the AM2302
+- Show time and weather information on the OLED
+- Keep the software structure easy to extend later
+
+## Notes
+
+The current hardware pin mapping is documented in [`docs/hardware-notes.md`](docs/hardware-notes.md). That file can be extended later with any extra electrical notes, display module specifics, or wiring photos if needed.
