Hello,
When I first installed and used the Arduino IDE, I couldn't get it to work as, when I tried to upload to the board, I was getting the message listed in the subject except that it was saying it couldn't find COM3. It was then that I searched and found that I needed to change the port in device manager from COM3 to COM1.
Since that time, everything has worked fine.
I've been using the Arduino IDE a lot the last few days and have done a lot of uploading. And today, for the first time I am getting an error saying it can't find COM1. This is despite the fact that I have set up the port in Device Manager to COM1.
As well as this, when I click on Tools in the Arduino IDE, the Port option is greyed out so I can't select anything.
Also, I could swear that in the past, in Tools, the Programmer option was set as "No Programmer".
However, now it has a programmer set and I can't unselect it to say there is No Programmer.
I have my board selected correctly as Arduino /Genuino Uno.
I would appreciate it if someone could help me understand what I'm doing wrong.
Cheers
Tony
