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...

How to Wire Arduino with LED The set up appears to be exactly similar to ourprevious RGB Arduino project, yes it is so, except the program which has been now changed for generating a random RGB LED light effect rather than the earlier sequentially flowing RGB color effect. The LED used he...
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...
