Where to start
- Download and unzip the folder.
- Read START-HERE.md for the tools, dependencies, and missing pieces.
- Open forcast_s3_mini/forcast.ino. Review the pin assignments at the top. Arduino may require the sketch folder to be named forcast.
- Check the configuration against your own hardware before building or flashing.
Build notes
Uses BMP280, DHT11, and SSD1306 sensors/display with the Adafruit and DHT libraries listed in START-HERE.md. The pressure-trend outlook is experimental; it is not a validated forecast or emergency warning.
These are workshop source snapshots. They have not been compiled or hardware-tested for this download. Original third-party notices remain in the files; no new blanket license has been added.
