本次设计提出了用AT89C51单片机为核心控制元件,设计一个简易的电子琴. 本方案以AT89C51单片机作为主控核心，与键盘、扬声器等模块组成核心主控制模块在主控模块上设有16个按键和扬声器.根据使用者的操作随意弹奏想要表达的音乐。
一首音乐是许多不同的音阶组成的，而每个音阶对应着不同的频率，这样我们就可以利用不同的频率的组合，即可构成我们所想要的音乐了，当然对于单片机来产生不同的频率非常方便，我们可以利用单片机的定时/计数器T0来产生这样方波频率信号，因此，我们只要把一首歌曲的音阶对应频率关系弄正确即可。

The design of the AT89C51 used as the core control components, Design of a simple flower. The program to AT89C51 as controlling core, and the keyboard loudspeakers core modules in the main control module on the main control module has 16 keys and speakers. According to users of the parade want to play for free expression in music.
Music is one of many components of different scales, each scale corresponds to different frequencies, This way we can use a different frequency combinations, which may constitute what we want music, Of course microcontroller to generate different frequencies very convenient, We can use SCM timer / counter T0 to create square wave frequency signals, therefore, As long as we put a song of the tune the frequency response relationship can get correct.
Keywords : microcontroller, buttons, speakers, chromatic.
