Rhythm master

简介

使用Arduino开发板制作出的一个简易钢琴演奏小游戏，依次按照顺序按动5个按钮，可使蜂鸣器发出“do”“re”“mi”“fa”“so”的声音。

所需硬件

Arduino开发板 X 1
电阻 X 6
连接线 X n
面包板 X 2
按钮 X 5
LED RGB X 1
蜂鸣器 X 1
1位数码管 X 1

具体实现

在arduino IDE端输入一段乐谱，通过1位数码管显示首个音符，玩家根据指示点击对应按钮进行该音符的弹奏；当玩家点击某个按钮后，数码管显示下一个音符指令；玩家按要求点击对应按钮后，LED RGB亮绿灯，若点击错误则LED RGB亮红灯，直到乐谱显示完毕。
