12 ultra bright smart LED 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.
