In this guide, you’ll learn how to control an RGB LED using the Arduino. An RGB (Red-Green-Blue) LED can produce a wide variety of colors by mixing different intensities of red, green, and blue light. You’ll learn to create a basic Arduino RGB LED circuit and cycle through some b...

前面的示例我们通过小爱同学控制了灯的亮灭,然后现在我们增加LED灯亮度、色温以及模式的控制。 特别说明:要实际控制灯的亮度和色温的话我们需要用到RGB灯,而且有些比较简单的GRB灯只能调节三色灯的亮灭,最多也只能调出8种颜色,如果需要调节出多种色温,还需要调节三色灯里面每一个灯的亮度。每个灯的亮度阶梯越多,能...

The article discusses a simple,Arduino red, green, blue LED light effect generator circuit in a random pattern. In one of the earlier posts we came across a similar RGB LED effect generator circuit using Arduino which was programmed to produce theeffect in a flowing sequential manner, whereas ...
We really like the range of LCDs we stock in the shop, such as our classic blue & white and the fancy RGB negative and RGB positive. Unfortunately, these LCDs require quite a few digital pins: 6 to control the LCD and then another 3 to control the RGB backlight for a total of 9 ...

在下图中,您可以看到LED内的芯片。LED是RGB LED,工作原理是这样的: 这种非常灵活,可以切成您想要的任何长度。如您所见,该条带分为多个段,每个段包含一个RGB LED: 您可以通过在合适的地方用剪刀剪裁条来调整其大小(标出了剪裁条的正确位置): 这些灯带的两端均带有连接器。我决定剪掉连接器和焊头引脚。如果您要...
