This course introduces students to the fundamentals of Printed Circuit Boards (PCBs) — essential components that support and connect electronic parts, often called the "mother of electronic products." Students will use EasyEDA, a web-based design tool that allows beginners to create circuit schematics and lay out PCB designs without requiring prior technical knowledge or programming experience.

By the end of the course, students will have completed a capacitive touch LED desk lamp. The project is powered by USB and features dynamic LED patterns (e.g., flowing light). Using a capacitive sensing chip, the PCB detects user touch input, allowing the lighting mode to be changed interactively. This course blends electronics, design thinking, and user interaction for a complete STEM learning experience.
