#51单片机实现的音乐闹钟程序代码
功能描述：产品可以显示时间和日期，时间格式为 hh mm ss 日期格式为 yy.mm.dd时间和日期轮流显示。
时间显示5S 日期显示3S。
可以设置5个闹铃，闹铃音乐可以设置两种：毛驴和童年。
三个按键对时间和闹铃进行设置，六个LED进行显示。
计时采用DS1307。
继电时间不丢失，设置过的闹铃也不丢失。
闹铃音乐由单片机的两个定时器去产生频率实现。
部分程序如下：//*************************************************//************************************************//***********************************************//程序名：DS1307 时钟程序//功能描述：用六个八段LED 轮流显示时间// 和日期。

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。

单片机蜂鸣器音乐代码
单片机蜂鸣器音乐代码在单片机的应用中，蜂鸣器是一个常用的音频输出设备。
它可以通过产生不同频率的声音来实现音乐播放、提醒和警报等功能。
本文将介绍如何使用单片机控制蜂鸣器播放音乐，并提供一个简单的音乐代码示例。
首先，让我们了解一下单片机蜂鸣器的工作原理。
蜂鸣器实际上是一个压电陶瓷元件，当电压作用于其上时，它会振动产生声音。
为了产生不同的音调，我们需要控制蜂鸣器的频率和占空比。
单片机通过IO口与蜂鸣器连接，并使用定时器来产生所需的频率。
具体的代码实现将依赖于使用的单片机型号和开发环境。
在这里，我们将以C语言为例，并基于51单片机进行说明。
以下是一个简单的单片机蜂鸣器音乐代码示例，演奏的是《欢乐颂》的前几个音符：```c#include <reg52.h>// 定义各个音符的频率#define C4 4778#define D4 4257#define E4 3792#define F4 3579#define G4 3189#define A4 2841#define B4 2531#define C5 2388// 延时函数void delay(unsigned int count){while(count--);}// 发声函数void beep(unsigned int frequency, unsigned int duration) {unsigned int i;unsigned long time;time = 11059200 / frequency; time >>= 1;for(i = 0; i < duration; i++) {P1 = 0x08;delay(time);P1 = 0x00;delay(time);}}// 主函数void main(){// 设置定时器TMOD = 0x01;TH0 = (65536 - 50000) / 256; TL0 = (65536 - 50000) % 256; TR0 = 1;// 播放音乐beep(C4, 100);beep(D4, 100);beep(E4, 100);beep(F4, 100);beep(G4, 100);beep(A4, 100);beep(B4, 100);beep(C5, 100);while(1);}```以上代码中，我们首先定义了各个音符的频率，这些频率是通过实验测量得到的，具体数值可能因蜂鸣器型号、电源电压等因素而略有差异。
