Arduino魔幻音乐盒

本帖最后由 MicroMaker 于 2017-5-14 09:32 编辑

       这个盒子可以不用按按钮就可以发出美妙的音乐。只要将手放在盒子上上下摆舞几下，你的耳朵里就会响起优美的音符，随着优美的音符响起，发出迷幻的光线，好像一个看不到底的时空隧道。                                                          它的原理是：打开开关，将手放置于超声波传感器上方，如果探测到在一个范围内，喇叭就发出一个音调；探测到在另一个范围内，喇叭就会发出另一个音调。同时，不同的LED发出不同的色彩。光线在镜子与单透膜之间无限反射，形成无数个影子。
整个小制作，分成五个部分：第一部分：先用超声波传感器测量超声波碰到手再返回的时间。第二部分：由主芯片发出不同频率的脉冲，使喇叭发出各种各样的音调。音符（共11个）：a3;b3;c4;d4;e4;f4;g4;a4;b4;c5;d5;第三部分：利用不同的ＲGＢ颜色配比，形成由30个LED组成的光带，用一面镜子做底板，单透膜作为面板，LED光带放在镜子和单透膜之间，光线在镜子和单透膜之间无限反射，形成许多光带的影子。第四部分：Arduino主芯片收到信息后，用公式计算出手与传感器之间的距离（公式：距离=时间*音速（340米/秒）/2）。按照不同的距离，主芯片命令发出不同的音乐、不同的LED发出不同的光。比如：距离为130mm，喇叭发出la(c)，第1、2、3、27、28、29号LED点亮。   第五部分：开发系统、开发板    本小制作采用了Arduino UNO开发板    主控芯片：ATMEGA 328p    编程软件为Arduino IDE    编程语言:C/C++
