本文介绍了如何制作一个Arduino架子鼓，包括硬件清单和最终效果。适合所有技术水平的创客，从产生好奇到动手实践的全过程。

来参加上海创客嘉年华的伙伴们有没有看到这个作品:lol

几位小伙伴问我开不开源，那不是必须的嘛~制作过程送上！

不好意西啦，交这个作业迟了点，都一个多月了...真的抱歉:shutup:

送上活动时候的照片（明和电机的社长大大真的好萌:loveliness:）

我早想做个电子鼓了，可一直停在想的阶段，大神都做出来了。。:'(

能有更详尽的电路图就好啦

fluidsynth is difficult.tell me how to use it please.:'(

你好能给我一分电路图吗？

又会玩音乐、又会造乐器、又长的帅~~简直就是：完！美！（请自行脑补金星老师动作）

哈哈哈，这算是表扬他吗？

好期待好期待！！！！蘑菇云来一套~~~来一套~~~~哟哟~切克闹！！

好赞~~~~顶一个先。。。。
后面仔细看了一下，原理没怎么讲，一般人是看不明白的，可能只多放了些照片。。。。。希望稍微具体些，就更完美了~~~~
视频也不错的~~~

剩下的就是自由发挥了:D，想怎么玩都可以

因为Windows有MIDI延迟的Bug，实时性相当不好（有专业声卡除外~）
Linux和Mac都没有这个问题
如果用Linux，可能需要这些软件（根据需要大胆配置~多种组合方案）
统统是免费或者开源软件哦:$

可以选择串口转MIDI（9600bps）或真MIDI（31250bps）两种波特率，看你怎么方便连接了~
各个板子的灵敏度在程序中也可以调节。
