【实例简介】

功能介绍：1.采用AT24C02芯片可以实现存储的密码掉电保存。密码为4位，只有在开锁时密码可更改，更改时要输入两遍确认；2.采用矩阵按键输入、1602液晶显示、LED灯模拟开锁，红灯亮绿灯灭表示关锁，绿灯亮红灯灭表示开锁。3.输入密码错误会提示错误次数，当次数大于3时，密码锁定，并发报警信号。4.超过一定时间没有输入（30秒），会自动返回LCD背光关闭，按任意键可打开背光显示输入。5.有密码还原键，当忘记密码时可还原到初始密码1111。矩阵键盘按键说明   1       2       3   确认键  4       5       6  手动关闭锁  7       8       9 修改密码 还原   0     删除键          X
