摘要
随着人们生活水平的提高和建立绿色城市的向往，音乐喷泉以其独特的魅力和特殊的 功能，愈来愈成为休闲娱乐产业中的一项重要产品,音乐喷泉的兴建也越来越多。根据目前 音乐喷泉的发展现状，本文将介绍一个以单片机为控制核心的小型音乐喷泉控制系统。
本文设计的音乐喷泉控制系统是以 STC89C52 单片机为控制核心的。音乐信号通过功 放芯片 LM386 进行放大，然后再由 ADC0832 芯片对音频信号进行模数转换，ADC0832 芯片再把转换后数字信号传送给单片机，单片机根据接受到数字信号的强弱来对应地控制 彩灯和喷泉的变化，从而实现了彩灯、喷泉水姿与音乐节奏的同步变化。经过硬件和软件 的调试，最终实现了音乐喷泉的功能。 关键词：音乐喷泉；单片机 STC89C52；发光二极管；模数转换
