LED Circle RGB 7 LED NEOPIXEL Compatible WS2812 5050 Board
These 7 RGB WS2812 LED NeoPixel Rings closely mimic the official Adafruit NeoPixel rings, allowing you to enjoy the same fun and versatility in your electronics projects. While not identical, they provide excellent performance for most applications except high-intensity lighting. With full RGB spectrum and individually addressable LEDs, these rings are perfect for ambient mood lighting, NeoPixel clocks, unique wearables, or creative projects like an “Arc Reactor” inspired by Iron Man.
Package Includes:
- 1 x 7-bit WS2812 5050 RGB LED
Additional Resources:
- The Official Adafruit NeoPixel UberGuide – details on NeoPixel rings, downloads, and resources.
- NeoPixel Jewel
- EagleCAD PCB files on GitHub
- Fritzing object in Adafruit Fritzing library
Arduino Code Example for 7 LED NeoPixel Ring (WS2812 5050 Compatible):
#include <Adafruit_NeoPixel.h>
#ifdef __AVR__
#include <avr/power.h> // Required for 16 MHz Adafruit Trinket
#endif
// Pin connected to the NeoPixels
#define PIN 6
// Number of NeoPixels in the ring
#define NUMPIXELS 7
// Delay between lighting each pixel (milliseconds)
#define DELAYVAL 500
// Create NeoPixel object
Adafruit_NeoPixel pixels(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);
void setup() {
#if defined(__AVR_ATtiny85__) && (F_CPU == 16000000)
clock_prescale_set(clock_div_1);
#endif
pixels.begin(); // Initialize NeoPixel strip object
}
void loop() {
pixels.clear(); // Turn all pixels off
// Light each pixel in sequence
for(int i = 0; i < NUMPIXELS; i++) {
pixels.setPixelColor(i, pixels.Color(255, 0, 0)); // Red color
pixels.show();
delay(DELAYVAL);
pixels.setPixelColor(i, 0); // Turn pixel off
}
}
