Developed the foundational LED Demo hardware design for the formulaslug/fs-3-intro-projects repository, delivering the first functional PCB and schematic for a demonstration circuit. Focused on electronics engineering and PCB design, the work involved creating a layout in KiCad that connects a resistor, LED, and battery holder, enabling hands-on testing and rapid prototyping. The approach emphasized clear documentation and commit traceability to support future hardware-software integration. By establishing a concrete hardware baseline, the project enables demonstration readiness and iterative development. No major bugs were reported, reflecting a careful and methodical engineering process centered on schematic capture and embedded hardware prototyping.
