WS2812 12 Bit RGB LED (round) The WS2812 12-bit RGB LED is a great way to add color to your Arduino projects. You can use it to create cool lighting effects, or add it to your existing project to add a splash of color. The WS2812 LED Strip is very easy to use, and its price is very reasonable.  The WS2812 RGB LED Ring light is can be easily used with Arduino Uno microcontroller. WS2812 5050 RGB 12-LED Round Lamp Development Board - Black Round and round and round they go! 12 ultra bright smart LED NeoPixels are arranged in a circle with (50mm) outer diameter. The rings are "chainable" - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together. Each LED is addressable as the driver chip is inside the LED. check out : WS2812 8 Bit RGB LED (straight)

WS2812 16 Bit RGB LED (round) The WS2812 is a 16-bit RGB LED that combines a full-color RGB LED and a control circuit into one device. The LED has a 5050 package, making it small and compact, and it is frequently used in LED lighting projects and other applications that require programmable colour control. Each LED has three color channels (red, green, and blue) and can produce a wide range of colors by adjusting the brightness of each channel. The LED is controlled by a single data pin, which allows for daisy-chaining multiple LEDs together to form a chain. This makes it easy to control large arrays of LEDs with a single microcontroller or microprocessor. It is compatible with a variety of microcontroller like Arduino, Raspberry Pi, and others. It supports the popular NeoPixel library, which provides an easy-to-use interface for controlling the LED. The LED operates over a wide voltage range of 4V to 5.5V and consumes low amount of power.

WS2812 16 Bit RGB LED Matrix You can create animations, and games, or even incorporate them into a fun e-textiles project. On top of all that, thanks to its flexible backing, this LED Matrix can be bent and bowed to fit onto almost any curvy surface. These panels require a 5V low voltage input for power which needs to be able to source a good amount of current. Each LED is capable of drawing as much as 60mA (at peak brightness the matrix can draw just over 3.5 Amps at 5 Volts), this adds up so it is suggested to use a 5V 2A power supply. There are two 3-pin connection ports to the wiring board. Solder wires to the input port and provide 5VDC to the +5V and ground pins, then connect the DIN pin to your microcontroller and make a common ground from the 5V power supply to the microcontroller/Arduino.
