What's cooler than smart RGB LEDs? Smart RGB+White LEDs! These NeoPixels pack 4 LEDs (red, green, blue, and white) for amazing lighting effects. This is the NeoPixel 1/4 60 LED Ring in Natural White. There are many other NeoPixel rings in our store. With four of these quarter - rings, you can create a large ring with 60 ultra - bright smart LED NeoPixels arranged in a 6.2' diameter circle. Each order includes just the quarter ring, and you'll need to solder four together for the full ring. The rings are chainable. Connect the output pin of one to the input pin of another, and use only one microcontroller pin to control as many as you can chain. Each LED is addressable as the driver chip is inside. They have a ~18mA constant current drive, ensuring consistent color even with voltage changes, and no external choke resistors are needed, making the design sleek. Power it with 5VDC. The NeoPixel is split, with one half being RGB and the other a white LED with yellow phosphor. They're incredibly bright when lit and can be controlled with 8 - bit PWM per channel (32 - bit color overall). Great for adding colorful and white dots to your project. NeoPixel LEDs use an 800 KHz protocol, and the PWM rate is ~400 Hz. DotStars have a 20 KHz PWM rate for smoother blending. NeoPixels are 5050 - sized LEDs with an embedded microcontroller inside. You can set the brightness and color of each R/G/B/W with 8 - bit PWM precision. They're controlled by shift - registers and need only 1 digital output pin for data. The PWM is built - in. We have a tutorial for wiring, power usage, and example code. Note that you'll need a NeoPixel library with RGBW support. Our Adafruit NeoPixel library supports it. One quarter ring of 15 individually addressable RGB LEDs comes assembled and tested. We recommend buying four for the full circle.
Using the NeoPixel 1/4 60 Ring is a breeze. First, if you want a full 60 - LED ring, you'll need to buy four quarter - rings and solder them together. Power the whole setup with 5VDC. Connect the rings by linking the output pin of one to the input pin of another, and use just one microcontroller pin to control them all. To set the color and brightness of each LED, you can use an 8 - bit PWM precision, giving you 32 - bit color per pixel. Just make sure you have a NeoPixel library with RGBW support. Our Adafruit NeoPixel library is a good option. If you use a plain 'RGB' library, you'll get strange results. As for maintenance, keep the rings away from excessive moisture and high - temperature environments. If an LED isn't working, check the soldering joints first. With proper use and care, these rings will light up your projects for a long time.
