我来消灭零回复{:soso__10469387108248471281_4:}

nice!

cool，这个老外年纪轻轻就秃顶了

没看懂程序，这是调用的MINI芯片里的信号发生器来产生的鼓声吗？

vblearn

应该是向波表发的MIDI信号，模拟出的鼓声。 MIDI实际上就是个串口。

这玩意很好玩，我本身也喜爱玩MIDI，有空搞一个来玩。
这是它的教程http://www.instructables.com/id/Arduino-Air-Drums/
代码与pdf文件https://github.com/bhar92/AirDrums
关鍵部分（MIDI软件）没有示范，很多人肯定看不懂。
MIDIS软件有很多，免费的也很多。
