WS2812 8 mm RGB LED

WS2812 8 mm Addressable RGB LED (Digital Controlled)

The WS2812 8 mm addressable RGB LED is an LED solution with an integrated control chip, operated via a single digital data line. Depending on the production batch, the product may include a WS2812 or WS2811 control chip. Both chips interpret digital signals transmitted over a single wire to determine the LED’s color and brightness values.

This product is different from standard (passive) RGB LEDs. It does not light up continuously by simply applying power. To operate, it requires a digital data signal generated by a microcontroller. Therefore, it must be used together with microcontrollers such as Arduino, ESP8266, or ESP32.

In single-unit use, each LED operates by reading the data packet sent to it. When multiple LEDs are connected in series, they can be addressed and controlled sequentially via the same data line. This structure enables the creation of animations, color transitions, and lighting effects.

For testing purposes, the presence of the control chip can be checked by applying 3–3.7V to the longest lead and completing the circuit using one of the other leads. In this case, the LED may light up steadily. However, a digital data signal is required for full control of color, brightness, and effects.

On the Arduino side, the LED can be easily controlled using libraries such as Adafruit NeoPixel or FastLED. Thanks to these features, it is widely preferred in decorative lighting, wearable projects, robotic applications, and custom LED designs.
