The WS2812 LED is an RGB LED that can produce almost any color available. This ring has 32 of these LED’s in a circle to produce amazing light effects.
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. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim.
