Embedded Password Security System Design
Date:
- Designed and implemented a microcontroller-based password security system using NUCLEO-L432KC and Mbed OS.
- Developed the embedded software in C++, utilizing UART communication between the microcontroller and PC for password verification and system feedback.
- Integrated LED indicators and a seven-segment display to provide real-time visual status of password correctness and system lock state.
- Implemented system logic allowing three password attempts, after which the system locks and requires manual reset via a push button.
- Conducted hardware prototyping and functional testing on a breadboard to verify system performance under multiple test scenarios.
- Achieved successful operation with accurate password validation, lock mechanism, and user feedback, demonstrating strong skills in embedded system design, hardware-software integration, and real-time control logic.
