Ok, I'm new to Arduino and I got an Arduino Uno ATMEGA328P. I have windows 7. When I was looking at a tutorial it said to click on the "Serial Port" tab, but mine is grey and I can't click on it. I thought it might have something to do with the fact that the "Add New Hardware wizard" didn't come up. Please help and thanks for your time.
(P.S.) I'm sorry if anyone already asked this question
