Digital Keypad Lock
A programmable 4-digit keypad lock written entirely in assembly.
For my embedded systems I class at MSOE, I designed a digital keypad lock using an STM32 Nucleo development board, a switch matrix keypad, and an LCD module. The lock features a programmable 4-8 digit code, with an LED simulating an actuator for unlocking. The entire system is coded in assembly.
