/* nastepne zadanie, na jutro bedziesz miał takie
 *  zrobic tak aby zmienna brightness zamienic na temperature tj zrobic zalezność swiatła od wysokosci temperatury... tylko to chyba bedzie dość trudne net chwile mi daj
 *  ustawiasz fade amount dla 20 stopni dla czujnika temp do max 36 (temperatura ciała człowieka)
 *  czyli if (temperatura == 20 )
 *          fadeAmount = 80;
 *        if (temperatura == 24)
 *          fadeAmount = 96;
 *        if (temperatura == 28)
 *          fadeoumnt  = 112;
 *
 *          rozumiesz? na razie tak, potem zbudujemy tablice PWM w liczbach całkowityh aby była płynna regulacja
