These NeoPixel rings are a fantastic addition to your projects! They feature smart LEDs arranged in a circle, making them perfect for creating eye - catching circular lighting effects. All our rings are chainable. Simply connect the output pin of one ring to the input pin of another and control multiple rings with just one microcontroller pin. Each LED has an in - built driver chip, making them individually addressable. With a ~18mA constant current drive, the color remains consistent even with voltage variations, and no external choke resistors are needed, resulting in a sleek design. Power the rings with 5VDC (4 - 7V also works). They use a single data line with a timing - specific protocol, so you'll need a real - time microcontroller like an AVR, Arduino, PIC, or mbed. Our well - written Neopixel library for Arduino supports these pixels. An 8MHz or faster processor is required. Our detailed NeoPixel Uberguide provides all the resources you need, including ready - to - use library and example code for different Arduino models. The rings may come with either WS2812B or SK6812 - based LEDs, which have the same brightness, color, and protocol.
Using these NeoPixel rings is easy. First, connect the rings together by linking the output pin of one to the input pin of another. Then, connect them to a real - time microcontroller such as an Arduino. Make sure your microcontroller has an 8MHz or faster processor. Power the whole setup with 5VDC (4 - 7V is also okay). Our Neopixel library for Arduino can help you control the LEDs easily. Just download the library and use the example code in the NeoPixel Uberguide. When it comes to maintenance, keep the rings away from water and extreme temperatures. If you need to replace an LED, be careful as they are delicate. And remember, since the protocol is timing - sensitive, don't use a Linux - based microcomputer or an interpreted microcontroller like the netduino or Basic Stamp.
