	"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)
}
