这小线飞的，真赞! 视频怎么是Youtube? 有密集恐惧症和缺乏耐心毅力者请勿模仿哈 厉害！膜拜 我焊的时候是一个一个用尺量的，焊得不错 视频只有9’’。 第一个视频只有9’’。 蛋疼的男人 谢谢楼主！！！ 楼主真心强大啊！ 楼主问一下你这个代码看的懂吗？？
还有arduino的i/o口是怎么接的，分别是哪几个i/o口接到板子上，哪几个接138？？哪几个接74hc574？？还有哪几个接地线？？
楼主问一下你这个代码看的懂吗？？

firrework(); 那是煙火的動畫程式
運算都寫在副程式裡
在loop裡用函數把它呼叫出來
這樣方便 隨意編排動畫順序
而不會導致 重復復製相同的程式 亂七八糟 讓自己看不懂
