摘　　要：基于声音的动感LED灯光具有简单便捷的展现方式与炫彩的灯光展效果,给人们带来独特的视觉感受。该文以STC89C52单片机设计声音动感LED灯,设计了两种根据声音的大小变化而改变LED彩灯的方案,通过音频信号线采集外部音源播放音乐的声音,采集后通过适当放大音频信号使信号更容易和准确地传输,最后将采集到的声音模拟量转变为可识别的数字信号传输到单片机中处理,由单片机识别数字信号从而通过P口控制输出端的LED彩灯,实现了随声而动的LED彩灯效果。Dynamic LED light based on sound conveys people's feelings of joy through vision with its simple and convenient display way and colorful light exhibition effect.In this paper,STC89C52 MCU is used to design the sound dynamic LED lamp,and two schemes are designed to change the color LED lamp according to the change of sound.The sound of playing music from an external sound source is collected through the audio signal line.After the collection,the signal can be transmitted more easily and accurately by appropriately amplifying the audio signal.Finally,the collected sound analog quantity is converted into recognizable digital signal and transmitted to the microcontroller for processing.The microcontroller recognizes the digital signal and controls the LED color light at the output end through the P port,realizing the effect of LED color light moving with the sound.
