单片机是把主要计算机功能部件都集成在一块芯片上的微型计算机。它是一种集计数和多中接口于一体的微控制器，被广泛应用在智能产品和自动化上，而51单片机是个单片机中最为典型和最有代表性的一种。
本课题选择89S51为核心控制元件，设计了一个日常生活中用到的音乐门铃系统。当功能按键按下，音乐响起，发光二极管随着音乐的节拍进行闪烁，LED显示相应的器初值。音乐演奏过程中再次按下按键无效，只有当音乐段结束再次按下才有效。如果是音乐门铃在响，按下复位按键就终止，显示初始状态。经过实践证明，本系统运行稳定，具有一定的实用价值。

SCM is a major piece of computer components are integrated into the chip micro-computer. It is a multi-interface and counting on the micro-controller integration, and intelligence products are widely used in industrial automation. and MCS-51 microcontroller is a typical and representative.

The topics chosen for the 89S51 control of the core components used in the design of a daily electronic music doorbell system. When the function button is pressed, the music sounded and the music beats with light emitting diodes for flickered. Initial corresponding LED timer. Musical process again pressed the button ineffective, and only when pressed again before the end of the music effectively. If the doorbell ring for electronic music, press the button on the reduction and termination, showed initial state. Practice has proved that the system is stable and has some practical value.
