Description: 课程设计题目：数字音乐盒
课程设计要求：1.利用I/O口产生一定频率的方波，驱动蜂鸣器，发出不同的音调，从而演奏乐曲（最少三首乐曲，每首不少于30秒）
2．采用LCD显示信息
3．开机时有英文欢迎提示字符，播放时显示歌曲序号（或名称）
4．可通过功能键选择乐曲，暂停，播放。
5．选作内容：显示乐曲播放时间或剩余时间
硬件电路：本设计中用到了89C51单片机，4*4键盘，蜂鸣器，16*2 LCD，七段
显示数码管LED。
原理说明：当键盘有键按下时，判断键值，启动计数器T0，产生一定频率的脉冲，驱动蜂鸣器，放出乐曲。同时启动定时器T1，显示乐曲播放的时间，并驱动LCD,显示歌曲号及播放时间。也可在LED显示歌曲号。
