Data bits representing RGB brightness are fed serially into the Din pin, and the chip strips out the first 24 bits (8 bits each for R,G,B) and sends the remaining bits out the Dout pin. The Din and Dout pins are where the magic happens. It has 4 pins: Vdd (3.5 to 5.3VDC), GND, Din and Dout. The WS2812B is just about the simplest device you could imagine, from a hardware standpoint. Here is a nice picture of a WS2812 from the good folks at You can clearly see the 3 LED dies as well as the onboard WS2811 controller. Most of the pictures I could find online show the older WS2812 part, which has a slightly different internal structure and which has 6 pins rather than the 4 pins of the WS2812B.

This article is available in PDF format for easy printing With combinations of RGB you can reproduce just about any color, so in a sense a controllable RGB LED is a universal LED. BTW, RGB stands for Red, Green, Blue, if you didn't know.

This is a surface-mount RGB LED with a built-in WS2811 driver chip in the LED package - you can see it plain as day, along with the R, G and B LEDs, when you look at the chip face. Remember how we started this tutorial series with simple blinking LEDs? Well there is a fairly new and very cool RGB LED on the block, known as the WS2812 (the WS2812B is the latest model). So I thought I'd post this to give readers time for some holiday lighting experimenting. And it deals with RGB LEDs, which are just very fun in their own right, especially these new parts.

It introduces a bit of assembly language programming, and demonstrates bit-banging a tight serial data protocol. This tutorial chapter is a bit of a detour, but I think an interesting and useful one.
