下面这个是电路图，图我没有画啊，不过我用仿真去做，应该跟电路图差不多了，你可以参考下，可以实现流水灯，闹铃，日期，时间，等功能，上面给你的是按照你的要求，另外我懒得改了所以多了个功能就是可以看日期，你看上面的程序，第一个按钮ch，按一下查看日期，再按一下查看温度（被删了，随机现在是随机显示一个数字），再按一下是流水灯，再按一下又回到时间，另外两个键key/key1；按key是选择锁定分还是时，如果你当前显示的是日期的话就是顺序锁定日，月，年，按key1调整，图上显示的是22点00分09秒，就这样了
设计方案的话..........呵呵，AT89S52+6个数码管+11.0592晶振+2个30P电容+3个按钮+1个10UF电容如图连接，你自己去写方案把，分数给那么少，就只帮你那么多了
