资料介绍

文章使用单片机芯片设计亮度可调和光色可变的LED灯。通过软件编程实现单片机芯片引脚输出PWM波形,从而实现LED灯的亮度调节和光色变化,再使用全国技能大赛单片机项目的指定设备亚龙YL-236的DAC0832数模转换芯片和LED发光二极管模拟调光台灯,进行实际验证。

In this paper, an LED lamp with adjustable brightness and variable color is designed based on AT89C51 single chip computer. Through software programming, the output PWM waveform of the pin of the single chip computer is realized, so that the brightness of the LED lamp can be adjusted and the light color can be changed. Then, the DAC0832 digital-to-analog converter chip of Yalong YL-236 and LED light-emitting diode analog dimmer lamp are used as the designated equipment of the National Skills Competition.
