基于单片机的艺术彩灯系统设计

摘要

本文设计了一种新型的艺术彩灯控制系统,该系统使用单片机作为控制核心,采用了PWM脉宽调制技术.在系统硬件电路中增加了过零检测,利用三极管电路控制彩灯颜色的变化和组合.改进了传统艺术彩灯制作工艺要求严格,色彩变化单一的缺点.通过实验,该系统运行稳定,易于扩展.%A kind of neon light control system is designed, the control core of this system is SCM, and the system adopts PWM pulse width modulation technology. It increased the zero-crossing detection, controlled change and eombination of neon light by using transistor circuit. The strictness of production process of traditional neon light, and the disadvantage of a single color change were improved. The new systems are stable and more versatile through the experiment.
