电子密码锁(源码+原理图+仿真图+论文+制作过程)
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
