-Descrierea software a aplicaţiei:
 Aplicatia utilizeaza 2 Arduino Uno, care comunica prin I2C.
 Fiecare are rolul sau:
- * Slave-ul primeste temperatura de la Master si o afiseaza pe LCD.
+  * Slave-ul primeste temperatura de la Master si o afiseaza pe LCD.
- * Master-ul reprezinta efectiv alarma de temperatura.
+  * Master-ul reprezinta efectiv alarma de temperatura.
+Mediu de dezvoltare:
+  * Arduino IDE
+  * Tinkercad
