I have this code which animate an object of opacity 1 to 0 .

But I want to know how I can do to make this action is repeated infinitely, each 1 second ?

Any ideas ?

```
var tl = new TimelineMax();

        tl.add(timeLine_parpados.to($parpados,0.1,{opacity:1})); // parpados aparecen
        tl.add(timeLine_parpados.to($parpados,0.1,{opacity:0})); // parpados desaparecen

        tl.play();

```
