+Cazul 3: Pompa inactiva

+Au fost testate, de asmenea si cazurile in care temperatura este mai mare sau umiditatea este mai mica decat valoarea definita, o simulare live a fost dificil de obtinut.
 ===== Concluzii =====
+Always solder your LCD display, a fost destul de straight-forward proiectul, nu am avut probleme cu componentele, bibliotecile etc. A fost destul de interesanta realizarea unui proiect functional cu un arduino.
