Description NeoPixel Ring - 12x 5050 RGBW LED – Cool White ~6000K
This is a NeoPixel ring from Adafruit. It contains 12 ultra bright RGB NeoPixels arranged in a circle. The ring has an outer diameter of 37mm. The rings are chainable. Connect the output pin of one to the input pin of another. You only need one microcontroller pin to control as many rings as you can chain together .
This variant comes with a cool white RGBW version. The ring is also available with natural white and warm white.
This variant comes with a cool white RGBW version. The ring is also available with natural white and warm white.
Each LED is addressable because the driver chip is on the LED itself. They each have ~18A of constant current drive, which makes the color very consistent. Even when the voltage varies. You don't need any external choke resistors, which makes the design slim. Just power it with 5VDC and you're good to go.
It uses a single data line with a very timing specific protocol. Since the protocol is very timing sensitive you will need a real time microcontroller. Examples include Arduino, AVR, PIC, mbed, Raspberry Pi . It cannot be used with a Linux based microcomputer or interpreted microcontroller like the NetDuino . Adafruit has a NeoPixel library for Arduino which makes it easy to use. An 8MHz or faster processor is required. Wiring tutorials are available on the Adafruit site .
