Arduino小项目设计（蜂鸣器与呼吸流水灯结合，以及led点阵）
这还是在禹州那边弄的，应该是在10月8日的时候，怀念一下当初的设计。
我们的蜂鸣器弄的音乐是自己在乐谱上扣的，如果想要学习请点击以下，
学习怎样Arduino蜂鸣器演奏音乐
目录
1.led8*8点阵
2.这是我们的蜂鸣器音乐（当然不可能只是简单的音乐，这其中的led灯会跟随着音乐的频率进行流水以及呼吸）
3.这是我们的呼吸三位数码管（数字跑的时间会加快，以及在666和888会进行变速的呼吸）
4.最后放几张图怀念一下
1.led8*8点阵
学习点阵，学习8*8点阵（引脚的连接和这个是一样的）
其实先在8*8开发板上设计好相应的图案然后转换每一列装换成对应的16进制，这个可以用字模提取器进行提取
代码看我写的注释，理解一下
