## Getting Started

To use FastLED, you need to:

1. **Include** the library: `#include <FastLED.h>`
2. **Define** your LED array: `CRGB leds[NUM_LEDS];`
3. **Initialize** in setup(): `FastLED.addLeds<LED_TYPE, DATA_PIN>(leds, NUM_LEDS);`

### Advanced Features

- Use [color palettes](https://github.com/FastLED/FastLED/wiki/Colorpalettes)
- Apply *color correction*
- Implement **smooth animations**

```cpp
// Example code
void rainbow() {
    fill_rainbow(leds, NUM_LEDS, gHue, 7);
    FastLED.show();
}
```
