Rroy Chou developed the foundational LED Demo hardware design for the formulaslug/fs-3-intro-projects repository, delivering the first functional PCB and schematic for a simple LED demonstration circuit. Using KiCad and applying skills in electronics engineering and PCB design, Rroy created a board that connects a resistor, LED, and battery holder, enabling hands-on testing and rapid prototyping. The work established a concrete hardware baseline to support future hardware-software integration and demonstration readiness. All deliverables were thoroughly documented with clear commit traceability, ensuring maintainability and facilitating future iterations. No major bugs were reported, reflecting careful planning and execution during the project.
