摘　　要：针对如何去丰富人类的生活娱乐,本文研究了以AT89C51单片机来控制PWM波为核心的音乐喷泉系统。该系统包括音频信号放大模块和A/D数模转换模块,其功能是处理输入系统的音乐信号,并送入51单片机进行识别。采用Keil4进行软件设计,采用AD14进行系统设计实验。该系统通过单片机输出可变的PWM波,进而控制LED灯亮度以及闪烁频率、同时控制水泵电机转速,实现音乐节奏与喷泉灯光配合过程中的同步性。In view of how to enrich human life and entertainment,this topic studies the music fountain system with AT89C51 single chip microcomputer controlling PWM wave as the core.The system also includes audio signal amplification module and A/D digital to analog conversion module.Its function is to process the music signal input into the system and send it to 51 single chip microcomputer for identification.The software is designed with AD14,and the system design experiment is carried out with AD14.The system outputs a variable PWM wave through a single-chip microcomputer,and then controls the brightness and flicker frequency of the LED light,and controls the rotation speed of the water pump motor at the same time,so as to realize the synchronization between the music rhythm and the fountain light.
