NeoPixel Ring - 16 x 5050 RGB LED with Integrated Drivers

You can control these LEDs by using only one microcontroller pin. 16 ultra bright smart LED NeoPixels are arranged in a circle. The rings are 'chainable' - connect the output pin of one to the input pin of another.

The LEDs have 24-bit color resolution. The board operates in 4-7V DC voltage (5V recommended). It needs 20mA of current per pixel. They are driven by a constant value of current so even if your battery goes low, your NeoPixel's brightness level never reduces. You can drive NeoPixels up to 500 of them, in 30FPS rate by using Arduino. Arduino's process capability and memory sizes will not allow you to drive NeoPixel more than 500.
