这是一个51单片机小程序，功能是实现跑马表，只有三位。(This is a small program the microcontroller 51, the table function is to achieve the Happy Valley, only three.)

这是24L01台产资料，详细介绍了24L01如何使用，还有一些教程。(The machine is 24 l01 production data, 24 l01 was introduced in detail how to use, and some tutorial)

编写一段程序 统计从1000年到1999年之间闰年的个数 最后输出到屏幕上来(writing a program to sum up the numbers of leapyear between 1000 and 1999.Finally,showing the result on the screen.)

自动交通控制系统用红、绿、黄三支共两组发光二极管表示交通信号灯，利用单片机模拟有时间显示的定时交通信号灯控制管理。信号灯的变化规律可如下： 1）放行线：绿灯亮放行25秒，黄灯亮警告5秒，然后红灯亮禁止。 2）禁示线：红灯亮禁止30秒，然后绿灯亮放行。 3）当某一方向的红灯亮时，若该方向有车通过，则用扬声器声报警。（撞红灯信号可用3-5V模拟量表示）(Automatic traffic control system using red, green, yellow light-emitting diodes, said a total of three traffic lights, the use of single-chip analog time display on a regular traffic signal control and management. Changes of lights to be as follows: 1) Release Line: green clearance 25 seconds, the yellow light warning for 5 seconds, then the red light is prohibited. 2) ban shows lines: the red light is prohibited for 30 seconds, then the green light to release. 3) When the red light in one direction, if the direction of the car through, the alarm speaker sound. (Hit the red signal available 3-5V analog representation))
