Through the analysis of the functional requirements of the password lock, a smart password lock system that can realize functions such as unlocking and changing passwords is designed. By controlling the input and output of the circuit board using a single-chip microcomputer, the functions of password input and verification are realized. In terms of software design, the program is written in C language to achieve functions such as password storage and comparison. Finally, a practical circuit board prototype is made through the PCB diagram, and testing validation is carried out, proving the feasibility and stability of the intelligent password lock system.
