电子密码锁设计，实现四位密码开锁，可改密码(Electronic password lock design to achieve four bit password lock, password can be changed)

基于MSP430舵机控制程序，SG90舵机，由PWM进行控制(MSP430-based steering control procedure, SG90 servos controlled by the PWM)

该防盗系统使用热释电红外传感器作为人体探测模块，并将防盗系统设计为两个用户可选择的模式：在家模式和离家模式，当处于在家模式时，如果传感器检测到有人进入监控范围，则自动响起门铃提醒用户有访客，就不会发生误把访客当作盗贼的报警事件了；当处于离家模式时，如果传感器检测到有人进入检测范围，则开启声光报警模块进行报警。同时，该系统为密码控制系统，用户通过输入正确密码才可改变模式和解除警报，这也增强了该系统使用的可靠性。(The anti-theft system using pyroelectric infrared sensor as the detection module, and alarm system design for the two user selectable mode: home mode and home mode, when in the home mode, if the sensor detects a person into the monitoring range, will automatically alert the user to a visitor rang the doorbell, will not happen take the visitor as an alarm event of thieves; when in the home mode, if the sensor detects a person into the detection range, open alarm alarm module. At the same time, the system is a password control system that allows users to change their mode and lift their alarms by typing in the correct password, which increases the reliability of the system.)

实现密码锁的设计，通过LCD12864实现密码锁的设计，有密码修改等功能(mimasuosdijvsgdsfgfsgeggegegegergregeg)
