détection appui long ou court avec arduino

int compt=0;

const int Bouton = 2;
const int ledV = 3;
const int ledR = 4;

}

void loop() {


if (appuieLong()==1)

}
else

}

}



int appuieLong()
{
etat = digitalRead(Bouton); //lecture de l'etat du bouton. si il est pressé etat = high
while (etat == HIGH ) // tant que le bouton est appuyé
{

    delay(750); // delai de 750ms
    compt=compt+1;  //
}   
    if ( compt >= 2 ) // si superieur a 1.5s appui long
         {

         }

        }
}

Si vous pouviez me faire un retour. merci.
