如何用单片机做流水灯
因为电路用单片机控制，所以电路非常简洁。其电路原理图见下图，印制板图如下图所示。
电路的核心部分是AT89C2051单片机，前面提到它有Pl和P3两组I/O口，我们这里只用到Pl口，共8个引脚。图中Cl、R9组成典型的上电复位（即在加电时单片机复位）电路，XTAL、C2、C3与AT89C2051片内振荡电路组成时钟振荡器。值得注意的是，C2、C3的容量不能与图中数值偏差太大，否则可能引起不起振或振荡不稳定。XTAL的频率可以在4-20MHz之间，不过，频率的变化会导致程序运行速度的变化，这样就需要调整延时子函数的参数。事实上，不调整参数亦可，只是此时延迟时间不再是1秒，其延迟时间会随着XTAL频率的降低而增加。
二、软件部分
本程序包含两个函数，一个是主函数，另一个是延时子函数。源程序如下（为了便于讲解，我们为每行程序加上了编号）：
程序各行作用如下：
00行：把AT89C2051的头文件“AT89x051．H”包含进来。
01行：声明Delay（）延时子函数，该函数有一个无符号整型参数k，同时函数前面的void表明函数不返回函数值。
02行：延时子函数的开始，同时声明两个无符号整型变量i和j。
不过请注意，这里没有象上期的程序一样，把表示函数开始的“{”单独成行，而是把下一行写在一起了。事实上，写C程序的时候，可以把多行写作一行，C编译器只要遇到分号就认为是一行语句的结束。
当然，我们不能因为C程序有这个特点，就随意把多行合作一行书写，实际书写C程序的时候，还是要养成良好的程序书写习惯，按照约定俗成的原则来书写。
03行：声明for（）循环。这个循环的初始条件是i=0，终止条件是i＜k，循环计数是每循环一次，用手计数的变量i加1。因此，这个循环的循环次数就是k次。这样，只要改变k的值（即改变Delay（）延时子函数的参数k的值），就可以很容易地控制循环次数，从而获得不同的延时时间。
04行：声明嵌套在03循环中的一个新的for（）循环，这个循环与上一个循环相似，其循环次数是120次。本循环与上一个循环嵌套后，使得总的循环次数达120×k次。
05行：第一个分号，表示L条空语句，占用一个机器时间，以实现延时的目的。后面的两个“}”中，第一个“}”是04行for（）循环的结束标志，程序遇到它时，将自动返回04行，使用于循环计数的变量j加1，同时判断j是否小于120，如果否，则转入05行；第二个是03行for（）循环的结束标志，程序遇到它则会返回03行

Photo cards will be facing on their hometowns on the reading machine, pushed to the floor
After the adoption of authentication, access roads will open the door, get documents to enter the channel
Feet stand-channel Central footprints, the eyes at the screen
In order to ensure rapid assessment system, please take the initiative to remove the hat, scarf, glasses
If you have fingerprints collected at other control points, please take the initiative by fingerprint
Validation after the adoption of open access goalkeeper, so that customs clearance procedures on the completion of this easy
The whole process, you only need: First, credit card and second, three-bit authentication. Easy three-step, Come and experience it
Thanks to the use of self-clearance system
