- electronic code lock; 1602 LCD; single-chip microcomputer.
Starting from the point of view of simple and practical, using STC89C52 and low power CMOS type Eý PROM AT24C02 as main control chip and the data memory unit, combined with external matrix keyboard input,1602 LCD, alarm, unlock and other circuit modules to make electronic code lock is introduced in this paper. It can achieve the following functions: unlock when enter the correct password; alarm when enter the wrong password; code can be changed according to users' needs. The design method of code lock is reasonable, simple, safe and practical, with low cost, high flexibility, confidentiality and other advantages, which has a very good promotional value.
