     * In functia loop() am citit datele venite de la Arduino caracter cu caracter si am construit valorile initiale citite de senzori. In continuare realizam de fiecare data conectarea catre server cu asteptarea aferenta inainte de a incepe o noua transmisie catre server. Functia getValue() prelua stringul meu, separatorul care am ales sa fie virgula, si indexul pentru valoarea pe care o doream din string, valoare aflata intre 2 virgule consecutive.
