This allows a communication via a one-wire interface. These LEDs have an IC built right into the LED. This LED strip is made by WS2812B LEDs wired in series. You can control the brightness and the color of each LED individually, which allows you to produce amazing and complex effects in a simple way.
In my opinion, this is the coolest type of LED strips. So, they can be left outside at the rain and dust without any problem.
It is 5 meters long and the LEDs are enclosed in a weatherproof silicone. In the following figure you can see my WS2812B LED strip. You can visit Maker Advisor and find the WS2812B RGB LED Strip best price. Choose the one that best fits your purposes. The WS2812B addressable LED strip comes in several models that differ in size, sealant or LED density. The information in this post also works with other similar LED strips, such as strips of the WS28XX family, Neopixel strip and others.
