原创 DIY基于51单片机的旋转LED数字电子钟(红外线遥控调时)

在网上看到不少老外做的各种旋转ＬＥＤ显示屏，非常ＣＯＯＬ，我也动手用洞洞板试做了一个类似的显示屏，结果感觉还不错。于是再接再励继续努力，将作品进一步改进，完善后制成如今这个样子。

                                     就是这种古董软驱

                                       软驱上的直流无刷电机

                                                                                        拆开后的电机

仔细拆开直流电机，将带圆盘的铝轴从中开孔，让它刚好能插入一个插头。

                                                                             将旋转轴加工成这样

                                                                            装配好以后

按拆开时的顺序，反序将轴安装直流电机上。

                                                                                   电机装配完成后

用两片铜片做的电刷

                             电刷装好后的侧面图

将电路板上较突出的元件改焊在反面，

电机的电源接法。

 

二。电路板的制作

　　本制作品用５１单片机控制，具体电原理图如下：

 

用Protel 99设计制作了电路板。

 

 

最后得到完成的作品。

 

遥控器用的是松下车载机的，只用了其中的六个键。

 

 

三。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。
