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.
