Developed a complete LED demonstration circuit as a KiCad project in the formulaslug/fs-3-intro-projects repository, delivering both schematic capture and PCB layout with custom footprints for an LED, resistor, and battery holder. Applied electronics engineering principles and disciplined wiring practices to create a basic, functional circuit, establishing a reusable hardware demo baseline for rapid prototyping and onboarding. Leveraged KiCad for schematic and PCB design, ensuring version-controlled hardware development. The project enabled hardware validation and provided a foundation for future introductory projects, focusing on clarity and maintainability. No major bugs were reported, reflecting careful planning and execution throughout the development process.
