Developed the initial LED_DEMO PCB hardware design for the formulaslug/fs-3-intro-projects repository, establishing a reproducible foundation for hardware prototyping. The work involved schematic capture and PCB layout using KiCad, applying electronics engineering and hardware design skills to create a functional baseline for future iterations. To ensure data integrity and support rapid development cycles, a backup artifact strategy was implemented by packaging and committing the project files as a ZIP archive in the backups directory. This approach enabled reliable recovery and reproducibility of the hardware design, reflecting a methodical and process-oriented approach to early-stage PCB development and project documentation.
