Similar to the WS2812B LED, the module also has the power inputs, the data input, and the data output pins. WS2812B Neopixel Strip Module PinoutĪnd here is the pinout of an 8Bit WS2812B module. GND - Ground Connected to Ground pin of the Arduino.ĭO – Data Input from the microcontroller.ĭI – Data output to the next module or LED. VCC - Provides power for the module, Connect to the 5V pin of the Arduino.

The pinout of the WS2812B LED is as follows: The WS2812B LED has a total of 4 pins, among which two are for power, one for data in and the other for data out.

Apart from these two types of neopixels led we also have another version called the WS2812B RGB LED Matrix, we have already discussed on how to interface it with arduino so we will not be discussing it for this tutorial. Just like the previous module, all the LEDs are connected in series. The next image (shown below) is of a the RGB Neopixel LED Ring module with 16 addressable RGB LEDs in a circular formation. Similarly, the entire LEDs are connected one by one. The data in of the first LED is connected to the microcontroller pin and the DO or the data output pin is connected to the DI or the Data input pin of the next RGB LED. Each of these LEDs can be controlled individually using just one wire. The image below shows the RGB LED module with 8 WS2812B LEDs in series. The video below shows the working of an actual WS2812B LED. You can see that the WS2812B die is connected to 3 individual LEDs namely Red, Green and Blue using gold wires. The real-life closeup image of a WS2812B LED is given below. The table below shows the major differences between these popular controllers. There are many popular RGB-LED controllers available in the market including the WS281x Series, SK6812, SK9822, and APA102. But the major difference between them is the controller used in them. They come in different sizes and pinouts. There are multiple types of addressable RGB LEDs available in the market. Types of Addressable RGB LEDs - A Comparison We can build many Neopixel led projects previously, you can check them out if you are interested. We will be interfacing the WS2812B LEDs which are also known as NeoPixel. So, in this Arduino inerfacing tutorial series, we are going to look at how to interface such LEDs with Arduino. These addressable LEDs can be easily controlled by an Arduino. They provide you with more control options and fun effects to add even more glitz to your lighting setup. And even this standard is raised to a completely new level by addressable LED strips. Finding another lighting system that offers as much value and style would be challenging. They may be mounted almost anywhere, available in a variety of colours, and require very little maintenance. When you require a dynamic lighting solution, LED strips are a great choice.
