基于单片机控制的电子密码锁 摘要：本系统由单片机系统、矩阵键盘、LED显示和报警系统组成。系统能完成开锁、超时报警、超次锁定、管理员解密、修改用户密码基本的密码锁的功能。除上述基本的密码锁功能外，还具有调电存储、声光提示等功能，依据实际的情况还可以添加遥控功 -Based on MCU-controlled electronic code locks Abstract: This system consists of single-chip microcomputer system, matrix keyboard, LED display and alarm system. System to complete the unlock, overtime alarm, lock超次, administrators decrypt, modify the user s password locks the basic functions. In addition to the above basic code lock function, but also has a transfer electric storage, sound and light features such as tips, according to the actual situation can also add a remote control reactive
