## LED Indicator

As one of the simplest output peripherals, LED indicators can indicate the current operating state of the system by blinking in different types. ESP-IoT-Solution provides an LED indicator component with the following features:

* Can define multiple groups of different blink types
* Can define the priority of blink types
* Can set up multiple indicators
* LEDC and other drivers support adjustable brightness, gradient
* Support adjustment light with gamma
* Supports LED strips types like WS2812 and SK6812, and offers gradual color transitions based on the color wheel, brightness transitions, and the ability to specify LED index.

### Support LED Types
