This drivers allows interact with a RGB LED connected to a GPIO pin

## Documentation

For full documentation, please visit [![Go Reference](https://pkg.go.dev/badge/github.com/raspberrypi-go-drivers/rgbled.svg)](https://pkg.go.dev/github.com/raspberrypi-go-drivers/rgbled)

## Quick start

```go

package main

import (

	"fmt"

	"os"

	"time"

	"github.com/raspberrypi-go-drivers/rgbled"

	"github.com/stianeikeland/go-rpio/v4"

)

func main() {

	err := rpio.Open()

	if err != nil {

		fmt.Println("impossible to init gpio")

		os.Exit(1)

	}

	defer rpio.Close()

	rgbLED := rgbled.NewRGBLED(18, 27, 22)

	// Switch on the led an set it to lime green

	if err := rgbLED.SetColor("#a4eb34"); err != nil {

		fmt.Println(err)

		os.Exit(1)

	}

	time.Sleep(3 * time.Second)

	// Reduce the brightness to 50%

	rgbLED.SetBrightness(50)

	time.Sleep(3 * time.Second)

	// Switch off the LED

	rgbLED.SetBrightness(0)

}

```

## Raspberry Pi compatibility

This driver has has only been tested on an Raspberry Pi Zero WH using integrated bluetooth but may work well on other Raspberry Pi having integrated Bluetooth
