פיתוח בקר לדים WS2812B LED Strip EPS32

The WS2812B addressable LED strip comes in several models that differ in size, sealant or LED density. Choose the one that best fits your purposes.

In the following figure you can see a WS2812B LED strip. It is 5 meters long and the LEDs are enclosed in a weatherproof silicone. So, they can be left outside at the rain and dust without any problem.

This LED strip is made by WS2812B LEDs wired in series. These LEDs have an IC built right into the LED. This allows a communication via a one-wire interface. This means that you can control lots of LEDs using just one digital pin of your esp32.
