说明：  本课题切合现代智能家居要求，实现智能灯光控制，可以节约能源。本声光控制灯设计系统分为：（1）主控模块主要由单片机及其外围电路组成。（2）声音传感器主要由现成的模块，感应声音的音量，当达到一定声音值灯亮。（3）光感应主要由光敏电阻，感受不同的亮度值，转换成不同的电压，由ad转换后输入单片机处理(4)可以lcd显示其亮度值，（5）可以设定亮度值，并lcd显示出来，能够实现以下功能：（1）可以设置亮度值，当亮度低于设定亮度值时，led灯亮，（2）当外界声音达到一定音量是，led灯亮（3）lcd显示其实际亮度值与设定亮度值
(This paper meet the requirements of modern smart home, intelligent lighting control, energy conservation. The sound and light control lamp design system is divided into: (1) control module consists of the microcontroller and its peripheral circuit. (2) The sound sensor consists of ready-made modules, induction sound volume, the sound when it reaches a certain value lights. (3) The light sensor consists of photosensitive resistance, feel different brightness values, converted to a different voltage, input the MCU after the ad conversion process (4) can lcd display brightness value, (5) You can set brightness values and lcd is displayed, it is possible to achieve the following functions: (1) You can set brightness value, when the brightness is below the set brightness value, led lights, (2) when the outside sound reaches a certain volume 是, led lights (3) lcd display its actual brightness value and set brightness value)
