 ===Descriere generala===
 Proiectul va folosi un Arduino UNO si am ales sa folosesc senzori ultrasonici un buton care sa\\
-faca conversia din inch in centimetri si un buton de on/off. De asemenea, cand se apropie de\\
+faca conversia din inch in centimetri. De asemenea, cu cat se apropie mai mult de\\

+senzori aprind in functie de intervalul de distanta led-ul corespunzator,\\

+iar daca se aprinde becul rosu, setat la distanta cea mai mica, buzzer-ul emite un sunet puternic.\\

+Am realizat partea de coding in Arduino IDE. In functia senzor() calculez distanta de la senzor\\
+la obiect, pe care o transform in functie de modul setat din buton in centimetri sau in inch.\\
+Pentru a da o nota mai rezonabila buzzer-ului am folosit functia tone(), iar pentru a-l face sa\\
+bipaie am folosit un delay mic si apoi functia notone().\\

+Am implementat ce mi-am propus si functioneaza totul cum am sperat. Sunt multumit si a fost\\
+la fel de simplu pe cat ma asteptam.\\
