  Proiectul prezentat are ca obiectiv inregistrarea nivelului de gaze si afisarea
 acestuia pe un display led cu 4 cifre. Totodata, afisarea datelor se poate realiza si pe
-o aplicatie mobile, prin intermediul unui modul Bluetooth, existand si o notificare prin intermediul unui buzzer in cazul in care nivelul trece de un anumit prag.

 Initial mi-am dorit sa o realizez in Tinkercad, insa nu am gasit toate modulele asa ca am preferat sa realizez schema in Fritzing.
-Dupa cum se poate vedea si in schema, am pus rezistente, acolo unde a fost nevoie, astefel sa nu fie pus in pericol vreo componenta.

 Pentru programarea placutei am folosit Arduino 1.8.19, iar schema elctrica, cum am spus si mai sus am realizat-o in Fritzing.
+M-am folosit si de biblioteca "ezBuzzer.h", intrucat, initial, am incercat sa folosesc delay in redarea melodiilor, insa acesta, fiind blocant, imi intarzia transmiterea in aplicatie a valorii si afisarea pe display.
 Am programat Display-ul led, astfel incat sa-mi afiseze corect valorile primite.
-Totodata, am cosiderat numarul 800 ca valoare de referinta pentru declansarea buzzerului, astfel, cand senzorul transmite o valoare superioara, noi vom fi notificati.
+Totodata, am cosiderat numarul 700 ca valoare de referinta pentru declansarea buzzerului, astfel, cand senzorul transmite o valoare superioara, noi vom fi notificati prin inceperea melodiei Merry Christmas (am presupus ca vine Craciunul mai repede pentru persoana in cauza :)).
 Aplicatia mobila am realizat-o pe platforma MIT App Inventor.
