What is WS2812 Pixel LED
WS2812 is a type of individually addressable RGB LED
with a built-in driver IC. It’s widely used in LED strips, matrices, and pixel
displays due to its ease of control and vibrant color output. Here's a quick
breakdown:
🔧 Technical Overview
- Type: RGB LED (Red, Green, Blue)
- Controller: Built-in WS2811 IC inside
the LED package
- Voltage: Typically 5V DC
- Control: Single data line (one-wire
communication)
- Protocol: Proprietary timing-based
protocol (not standard I2C/SPI)
- Daisy-chaining: LEDs are connected in series,
and each one passes the data to the next
💡 Key Features
- Individually addressable: Each LED can be set to a
different color/brightness.
- Simple wiring: Just 3 wires — VCC, GND, and
Data In
- Fast refresh rate: Good for animations and smooth
effects
- Compact: Comes in small SMD packages like
5050
📦 Common Forms
- LED strips (e.g., 30, 60,
144 LEDs/meter)
- LED rings, panels,
and matrices
- Single LED modules for DIY projects
⚙️ Control Options
- Controlled using microcontrollers
like:
- Arduino
- ESP8266 / ESP32
- Raspberry Pi
- Libraries:
- FastLED
- Adafruit NeoPixel
