Description: 工作原理：
脉冲输入，记录30个脉冲的间隔时间（总时间），LED显示出来，牵涉到数码管的轮流点亮，以及LED的码。输入端口一定要用个
74LS14整一下，图上没有。数码管使用共阴数码管。MAXPLUS编译。
测试时将光电门的信号端一块连接到J2口的第三管脚，同时第一管脚为地，应该与光电门的地连接（共地）。
开始测试：
按下按键，应该可以见到LED被点亮，指示可以开始转动转动惯量盘，等遮光片遮挡30次光电门后，
LED熄灭，数码管有数字显示，此为时间值，单位为秒，与智能计时器的连续脉冲测试模式中的T30值进行比较。
再按下按键即可进行下一次测量。

Description: 单片机控制交通灯设计
十字路口车辆穿梭，行人熙攘，车行车道，人行人道，有条不紊。那么靠什么来实现这井然秩序呢？靠的是交通信号灯的自动指挥系统。交通信号灯控制方式很多。本设计主要分为五大模块输入控制电路、时钟控制电路、片内外程序切换控制、显示电路。以MSC-51系列单片机IntelAT89C51为中心器件来设计交通灯控制器，实现了AT89C51芯片的P0口设置红、绿灯、黄灯燃亮时间的功能；为了系统稳定可靠采用了74LS14施密特触发器芯片的消抖电路，避免了系统因输入信号抖动产生误操作；显示时间直接通过AT89C51的P2口输出，由CD4511驱动LED数码管显示红灯燃亮时间。-Single-chip microcomputer to control the design of traffic lights
