，最外侧的发光二极管就点亮一个瞬间一呈现时间刻度。

这样，如果在0.1s内这列发光二极管能旋转完一圈，则人眼就会产生错觉，而把先后产生的时间刻度连成12个完整的时间刻度。

明确系统功能

系统的功能比较清楚：

电机带动一系列发光二极管绕轴旋转，单片机控制发光二极管在旋转过程中的相应位置上点亮以指示时间和刻度，与此同时，单片机内部进行时钟的计时操作，以控制旋转时钟显示正确的走时。

这种利用机械的带动分时显示数据信息的方法叫做机械扫描显示。

硬件设计

旋转时钟主要有两部分组成：

电机部分和单片机控制发光二极管显示部分，在单片

本制作品用５１单片机控制，具体电路原理图如下：

软件编程

　　因学的是Ｃ５１（不懂汇编）这里只提供Ｃ语言源程序，并限制为无遥控功能。

也可提供带遥控功能的hex文件。
