51单片机c语言编写电子琴+音乐播放器
此程序是51单片机c语言编写的电子琴+音乐播放器，当用杜邦线将P1^0管脚接地时，单片机就会放出《世上只有妈妈好》，将P1^1 管脚接地时单片机就播放《祝你生日快乐》，两者为高电平时进入电子钢琴模式，利用16个矩阵键盘发出相应的哆、瑞、米、发、索。

单片机-利用蜂鸣器演奏音乐
实验三-利用蜂鸣器演奏音乐一、实验目的1.了解BlueSkyC51单片机实验板中蜂鸣器的硬件电路2.学会利用蜂鸣器实现音乐的演奏3.掌握蜂鸣器实现音乐演奏的编程二、实验硬件设计及电路1. BlueSkyC51单片机实验板2.单片机最小系统3.蜂鸣器电路连接三极管主要是做驱动用的。
因为单片机的IO口驱动能力不够让蜂鸣器发出声音，所以我们通过三极管放大驱动电流，从而可以让蜂鸣器发出声音，你要是输出高电平，三极管导通，集电极电流通过蜂鸣器让蜂鸣器发出声音，当输出低电平时，三极管截止，没有电流流过蜂鸣器，所以就不会发出声音。
三、实验原理1.音调及节拍用一个口，输出方波，这个方波输入进蜂鸣器就会产生声音，通过控制方波的频率、时间，就能产生简单的音乐。
一般说来，单片机演奏音乐基本都是单音频率，因此单片机奏乐只需控制音调和节拍。
（1）音调的确定音调是由频率来确定的。
通过单片机的定时器定时中断，将单片机上对应蜂鸣器的I/O 口来回取反，从而让蜂鸣器发出不同频率的声音。
只需将定时器给以不同的定时值就可实现。
通过延时，即可发出所需要的频率。
（2）节拍的确定一拍的时长大约为400—500ms,每个音符的时长通过节拍来计算。
详细见程序代码。
