Hi guys, thanks for the replies and help!
So I have connect the temperature sensor and everything was working good until my laptop turned off instantly while i was using the arduino connected to the USB. Now I cant turn it on 
I really dont undestand why, the laptop has only 3 months!!
It is possible that the arduino could burn it or something? For me its like impossible but I want to be sure.
Im sending it to ASUS to be fixed.
