I installed the Arduino Ide for windows. I checked everything, it seemed good, except for one thing. I had nothing selected on the "Port" Menu on Tools. I didn't know if it was too important, so i went on coding, it was really simple and short coding, so i know i didn't do it wrong. I even uninstalled it and re-installed the Program. It seems to me like the problem is the fact that there is nothing on "Port". How do i fix this? This is what popped up, please tell me what this might be do to: Thanks!
