Designed and assembled a custom ESP32-based IoT development board to simplify prototyping and testing of embedded systems. Integrated onboard power regulation/optional battery connect GPIO headers, on-board display for visualization, debug test-points, and programming interface for seamless firmware development and debugging.
Contributed to the redesign of a motor controller board for my university electric vehicle team, focusing on improving circuit layout, size, thermal performance, and phase-switching. I assisted in schematic review, component selection, and integrated an onboard temperature sensor. I collaborated with multidisciplinary team members in technical reviews to integrate the board into the new vehicle.
Designed and implemented a home-awareness system prototype using an ESP32, integrating Wi-Fi connectivity, GPIO control, and sensor monitoring through an onboard HTTP web server. The system streams real-time sensor data to ThingSpeak for cloud-based visualization and logging as well as provides on-board notification
I built a regulated dual-output (5V and 3.3V) DC power supply for powering microcontrollers and digital circuits during prototyping. Designed the circuit using linear voltage regulators, protection diodes, and filtering capacitors to ensure stable and noise-free outputs. Fabricated and tested the PCB to verify efficiency, load regulation, and reliability under varying current draws.
I demostrated a simple Bluetooth-enabled LED control system using an ESP32 development board to wirelessly toggle and adjust LED brightness from my smartphone. Implemented Bluetooth Low Energy (BLE) communication and GPIO control within the Arduino IDE. Demonstrated practical use of embedded communication protocols and wireless control in IoT applications.
This was my first solo project where I developed an interactive circuit badge using a 555 timer IC configured in astable mode to generate flashing LED patterns. I Implemented soldering and PCB design to highlight practical analog circuit design and timing principles. Emphasized compact design and visual functionality suitable for demonstrations or wearable electronics.
