The WS2812 (often sold as WS2812B) is an individually addressable RGB LED that can be controlled with a single Arduino pin. You can set each LED’s color and brightness independently, making it ideal for animations and effects.
Wiring the WS2812
VCC → 5V external power supply (not Arduino 5V if many LEDs are used)
GND → Common ground with Arduino
DIN → Arduino digital pin (through a 470Ω resistor)
Add a 1000µF capacitor across VCC and GND to prevent power surges.
Method 1: Using Adafruit NeoPixel Library
Step 1 – Install Library In Arduino IDE, go to Library Manager, search for Adafruit NeoPixel, and install it.
Step 2 – Example Code
#include <Adafruit_NeoPixel.h>#define PIN_WS2812B 4#define NUM_PIXELS 30Adafruit_NeoPixel strip(NUM_PIXELS, PIN_WS2812B, NEO_GRB + NEO_KHZ800);void setup() {strip.begin();strip.show(); // Initialize all pixels to 'off'}void loop() {for (int i = 0; i < NUM_PIXELS; i++) {strip.setPixelColor(i, strip.Color(0, 255, 0)); // Greenstrip.show();delay(100);}}Copied!âś•Copy How to Control WS2812B LED Strip with Arduino - LEDSuntech
