电子密码锁程序，两键输入，其中一个键累加，另一个键确认。密码正确锁打开（开锁指示灯亮）；密码错误锁关闭（关锁指示灯亮）；连续错三次则锁定键盘8秒并发出报警声。-Electronic code lock procedure, the two key input, one key additive, and the other button to confirm. The correct password to open lock (unlock indicator light) password error lock closure (Kuan-lock indicator light) consecutive wrong then lock the keyboard three times and issued eight seconds alarm sound.

将单片机的IOA0~IOA7分别接按键S1~S8连接到高电平上。此时，如果某个按键被按下，对应的I/O端口就会输入高电平进单片机，即按键S3按下，IOA2会输入高电平进单片机-Will Singlechip IOA0 ~ IOA7 access keys, respectively, S1 ~ S8 is connected to high on. At this point, if a button is pressed, the corresponding I/O port will enter into the high single-chip, that is, S3 button press, IOA2 will enter into single-chip high
