Built for the ATmega328-based board, it provides basic filesystem and system commands. The project is limited by the Uno's meager specs, making features like persistent storage or script execution difficult, but it demonstrates that there's still creative life in the aging platform. ## Full article daily.dev links to this article rather than hosting it.
