Design of password lock based on single chip microcomputer (designed in C language)

Design of password lock based on single chip microcomputer (designed in C language)

System Description

As shown in the figure, the system uses 80C51 single-chip microcomputer, ordinary keyboard, resistor array, and 1602 LCD.

The system features:

①When the correct password is entered into the system, the LED light will light up (in fact, many operations can be performed, and the LED is used only to represent the function. The main purpose is simple operation and obvious effect.)

② The system can modify the password; (After the system is powered off and restarted, the initial password (initial password is: 000000) must be used to change the password again. Of course, the modified password can be the same as before the power failure.)

Specific operations:

①When the system is turned on, a prompt will appear asking you to enter your password. Enter the password directly and press # to confirm.

②The system will automatically remind you that the password is incorrect, and after a few seconds the system will remind you to re-enter the password.

③In the interface where the system prompts you to enter your password, you can press the * key to modify your password. The system will prompt you to enter your password twice and check whether the two passwords are the same. If they are the same, the modification is successful. Otherwise, you can press the * key again to modify it after a few seconds.

④ Before changing the password (that is, after pressing the * key), the system will remind you to identify yourself. Please enter the old password. The system can only change the password after it determines that the old password is correct.
