An application for the ESP32-S3 board to trigger random sound-bytes.
The project is inspired by a "toy-button" that can be loaded up with MP3-files which it then plays randomly on each button press. Another big inspiration comes an online collection of sound-bytes accessible via a private RESTful API.
This project combines both: Pressing the button will fetch a random sound-byte from this online collection and play it.

- PlatformIO for building and flashing
- w64devkit for Windows development (GCC toolchain)
- Python for pre-commit hooks
The project comes with a dev-container configuration for Visual Studio Code. This allows you to develop inside a container with all necessary dependencies pre-installed.
If the PlatformIO integration fails, you can still build and run the project using the command line inside the dev-container (see below).
It seems that having the PlatformIO extension installed on the host-machine can cause issues with the integration. If you encounter problems, try disabling the extension in your host environment and reloading the dev-container.
This project uses PlatformIO environments defined in platformio.ini.
