Hi
I need help with my problem, which is that my arduino mega 2560 does not connect to the arduino IDE, the COM port does not appear at all, I tried another USB on the PC and another PC and still nothing, but another arduino worked, I don't know at all, please help me
Welcome!
I will take a SWAG and assume you are using windoze. If so it is probably the driver. If the Mega works on other computers that is a good indication of that. If it does not work on other computers the mega is probably bad.
I will say it is a bad Arduino, what did you do with it last time you used it?
