Smart RGBW LEDs! These NeoPixel rings have 4 LEDs (red, green, blue \u003cem\u003eand\u003c\/em\u003e white) for swish lighting effects.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis is the 16 LED RGBW NeoPixel Ring\u003c\/strong\u003e. \u003ca href=\"https:\/\/shop.pimoroni.com\/search?type=product\u0026amp;q=neopixel+ring\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eWe have a ton of other NeoPixel rings in the store to check out!\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e16 ultra bright smart LED NeoPixels are arranged in a circle with 1.75\" (44.5mm) 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. 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.\u003c\/p\u003e\n\u003cp\u003eThe NeoPixel is 'split', one half is the RGB you know and love, the other half is a white LED with a yellow phosphor. Unlit, it resembles an egg yolk. Lit up these are insanely bright (like ow my eye hurts) and can be controlled with 8-bit PWM per channel (8 x 4 channels = 32-bit color overall). Great for adding lots of colorful + white dots to your project!\u003c\/p\u003e\n\u003cp\u003eNeoPixel LEDs use 800 KHz protocol so specific timing is required. On NeoPixels, the PWM rate is ~400 Hz, which works well but is noticable if the LED is moving.\u003c\/p\u003e\n\u003cp\u003eNeoPixels are 5050-sized LEDs with an embedded microcontroller \u003cstrong\u003einside the LED\u003c\/strong\u003e. You can set the brightness and color of each R\/G\/B\/W with 8-bit PWM precision (so 32-bit color per pixel). The LEDs are controlled by shift-registers and only 1 digital output pin are required to send data down. The PWM is built into each LED-chip so once you set the color you can stop talking to the ring and it will continue to PWM all the LEDs for you.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/learn.adafruit.com\/adafruit-neopixel-uberguide\" target=\"_blank\" rel=\"noopener noreferrer\"\u003e\u003cb\u003eAdafruit have a tutorial showing wiring, power usage calculations, example code for usage, etc. for NeoPixel Please check it out!\u003c\/b\u003e\u003c\/a\u003e\u003cb\u003e Please note you will need a NeoPixel library with RGBW support\u003c\/b\u003e which is not always available.
