Embedded Circuit Design

Abstract

Over ten weeks, I designed and built a fully embedded WiFi‑enabled webcam system, from firmware to PCB to enclosure to website. The project integrated low‑level microcontroller programming, SPI/UART/I2C communication, camera interfacing, PCB development in EAGLE, and full‑stack web design. I implemented the WiFi and camera firmware, debugged synchronization and data‑transfer issues between the SAM4S MCU and ESP32, and validated the system through iterative testing on both breakout boards and custom PCBs. I also contributed to the mechanical design by creating a 3D‑printed enclosure with precise tolerances and functional access points for LEDs, buttons, and power.

This project strengthened my embedded systems intuition, from hardware bring‑up and signal integrity considerations to real‑time data handling and rapid prototyping. It reflects my ability to take a complex system from concept to a fully functional, user‑facing product, combining electrical engineering, firmware development, and practical design thinking into one cohesive build.
