DESCRIPTION
This LED Ring Light has 12/16/24 ultra bright smart LED NeoPixels arranged in a circle. The rings are 'chainable', which means you can connect the output pin of one to the input pin of another. It only makes use of 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. Power the whole thing with 5VDC (4 - 7V works) and you're ready to rock.
There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microcontroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp. An 8MHz or faster processor is required.
