I have been able to compile, but when I upload, an error comes up saying:

Binary sketch size: 10,786 bytes (of a 30,720 byte maximum)
processing.app.SerialNotFoundException: Serial port 'COM1' not found. Did you select the right one from the Tools > Serial Port menu?

I am also not available to choose a serial port, for it is grayed out..

Unplug then replug usb then serial com shouldn't be grayed out. If that doesn't work then try another usb port...

I tried unplugging and replugging, but there is no change, and Serial Port is still grayed out. I also did the same for the other usb ports but it still won't work
