密码锁:根据设定好的密码，采用二个按键实现密码的输入功能，当密码输入正确之后，锁就打开，如果输入的三次的密码不正确，就锁定按键3秒钟，同时发现报警声，直到没有按键按下3种后，才打开按键锁定功能；否则在3秒钟内仍有按键按下，就重新锁定按键3秒时间并报警-Password Lock: According to set a good password, the password used to achieve two key input function, when to enter the correct password, the lock will open, if entered incorrect password three times, on the lock button 3 seconds, also found that alarm sound, do not press the button until the three kinds of after the Open button lock function otherwise, there is still a matter of seconds in the 3 button press, on the re-lock button 3 seconds time and alarm
