I have a problem with the serial port.
So I have attached the USB cable to my PC, and when I compiled my code, the error says the serial COM8 is not found and it suggested me to set up the serial port. (Tools>Serial Port) But apparently, the serial port was grey out. So I am not able to do something with the COM 8 setting up. Does anyone has ever got similar issue? Please tell me, how do you finally overcome the issue!
