RGB Large LED Ring 15 Bit WS2812 5050 RGB LED with Integrated Driver
Use only one microcontroller pin to control as many as you can chain together!
A 4-piece chain will give you a ring diameter of 78mm.
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.
Power the whole thing with 5VDC and you're ready to rock!
