WS2812B led strip

🌈 WS2812B Addressable RGB LED Strip

The WS2812B is a digital, individually addressable RGB LED built with integrated driver ICs inside each LED.

Each LED can be controlled individually for color and brightness.

Controlled via a single data line using serial protocol (like NeoPixel).

Perfect for decorative lighting, displays, signage, costumes, and IoT projects.

Can be chained in long strips — hundreds of LEDs can be controlled with one microcontroller pin.

✨ Key Features

✅ Individually addressable RGB LEDs
✅ Single-wire digital control (DIN)
✅ Wide color range (24-bit, 16 million colors)
✅ Adjustable brightness
✅ Chainable (long strips)
✅ PWM frequency ~400 Hz
✅ Low cost, widely used in DIY & professional projects
✅ Compatible with Arduino, ESP32, Raspberry Pi, and more

Pin Function
+5V Power (5V DC)
GND Ground
DIN Data Input (connect to microcontroller output pin)

Optional (for some strips):

DO → Data Output (to next strip)

⚠️ Important: Data direction matters — DIN → microcontroller → LEDs → DO → next LEDs

🔌 Wiring Example (Arduino)
WS2812B Pin Arduino Pin
+5V 5V (or external 5V if many LEDs)
GND GND
DIN Digital pin (e.g., D6)
Notes:

For long strips (>20 LEDs) → use external 5V power supply

Place capacitor (1000µF/6.3V+) across 5V & GND to stabilize voltage

Place resistor (~330Ω) in series with DIN for signal protection

Example Arduino Library:

Use Adafruit_NeoPixel or FastLED library

Control each LED individually with code
