Each LED receives its data, then passes the next packet of data along to the next one. The WS2812B chip takes care of the LED driving, and we just send it data to tell it what the LED colour should be. How Do They Work?Įach LED package looks the same as a standard 5050 package LED, however packed in there is a tiny circuit with the controller chip, and an individual LED for each colour. Today we’ll be using examples with the WS2812B version, however the examples are fairly easily adaptable to the WS2812. They both use the same communication protocol, however the timings are slightly different. That’s right, you can control an entire string of these, all from a single pin! The standard WS2812 has 6 pins, only one of which is used for data, however the alternate WS2812B is used more commonly and has only 4 pins in a 5050 SMD package. They allow you to have as many LEDs connected in series as you want, all controlled by a single wire from a microcontroller. The WS2812 is one of the most popular digitally addressable RGB LEDs and is used in thousands of products today, as well as DIY and maker electronics.
