那个子模提取的软件是你们自己编的吧。。
好强啊!!
想问一下那么多的线怎么连到电机的叶片上去啊?
就是说如果直接连线的话肯定会打结,使用电刷吗??
还是有什么更好的办法啊??
谢谢!!!

呵呵。。。
电刷是一种方法,最起码如果你不用电池的话,外接电源就必不可少的用到电源的两个电刷。
我们是用的电池,然后把电路都接到一块板上,然后跟灯一起旋转,跟点机部分脱离关系,这样就可以解决这个问题,但要注意不要偏心,否则晃动厉害。

哇!!顶!!
你们效率好高啊。
刚问的就回答了。
那你们的二极管是只接在一个叶片上还是接在多个叶片上呢??
而且是接多少个比较合适呢??
再次谢谢!!!

一般般啦。。。
发光二极管只要接到一个叶片上就可以啦。。。
因为显示一个汉字你需要至少是12×12的,一般都要做到16×16点,你需要用至少16个发光二极管,这样此啊能显示一排完整的汉字。。。
