单片机音乐控制流水灯.docVIP

摘 要 本设计是一种基于AT89C51单片机音乐控制彩灯的方案，实现单片机演奏音乐，并且对LED彩灯随音符频率的不同而闪烁发光。本方案以AT89C51单片机作为主控核心，利用三极管和蜂鸣器，通过三极管放大电流使用蜂鸣器播放音乐，利用编程实现亮灯循环模式，在有8个LED彩灯,根据用户需求可以编写若干种亮灯模式.例如左右闪烁，隔几个亮灭，蜂鸣器可以根据用户需求改写编程播放各种音乐。本方案具有设计简单、体积小、元器件少、电路结构简单等优点。该设计方案设计及其简单，典型的89c51单片机，亮灯模式多，播放各种类型的音乐，具有体积小、价格低、低能耗等优点。在美丽的都市夜晚，彩灯的循环亮灭，播放动人的音乐，衬托出美丽的氛围，音乐彩灯具有更广阔的发展天地。 关键字：AT89C51 LED彩灯 音乐 Abstract This design is a musical based on AT89C51 microcontroller control program Lantern，realize MCU playing music，And the LED lights on the frequency of different notes with the light flashing。The program for AT89C51 microcontroller as the control center, use of transistor and buzzer, the current through the transistor amplification using the buzzer to play music, Using programming lighting cycle mode, with 8 LED Lantern, according to user needs to write some kind of switch-mode. For example, flashing around, every few light off, the buzzer can be adapted according to user requirements play a variety of music programming . The program is simple in design, small size, less components, and simple circuit structure. The design and simple design, the typical 89c51 microcontroller, a switch-mode and more, playing all types of music, has a small size, low price and low power consumption and so on. In the beautiful city at night, lanterns light off cycle, play beautiful music, brings out the beautiful atmosphere，music Carnival with the development of a broader world.
