I am using Window 10. I have followed the instructions. I connected from a USB port to my Arduino Nano. I set up the board to NANO but Port was greyed and did not let me set to anything. I did not pay much attention because the port was a USB and when I installed the IDE I also installed a USB driver that came with it so I thought it has recognised it. (By the way the green light on the Arduino is on by now. So I tried the Blink program, I compiled it but when I tried to transfer to the Arduino it failed. Then I went to check what ports are defined in my computer but the system administrator does not show ports. This was on my laptop. I repeated the whole thing on a desk top thinking that the problem was with the computer only to find the same thing happening. Both computers are relatively new. And the Arduino I am using is a NANO V 3.0. I am new to the Arduino and this is my first project. Can anyone help me please. Is it possible that there is something wrong with the cable.
By the way, I need to solve the problem soon since this is for a school project and will appreciate any assistance,
