Hello!
I was constructing the lightmusic using this plan.
I applied 12V from the power supply and connected the board to PC in order to see the Serial data, but I got an error saying that the COM port wasn't found.
I disconnected all the cables from Arduino. After that it doesn't appear on the PC by any means, COM port doesn't appear in the IDE. I tried using other USB ports but there was no result. However, after connecting Mega, everything started to work again. Tell me please, did I "burn" Arduino Uno completely?
did I "burn" Arduino Uno completely?
Well maybe not completely but perhaps just the processor that does the USB to serial conversion.

That is, can throw away and buy a new one?
Suggestion: throw away the Uno and buy a new Uno.
In theory, you can replace "just the processor that does the USB to serial conversion" but:
- You have to be good at desoldering and soldering surface mount devices, AND
- It is an assumption that the only thing "burned" is the processor that does the USB to serial conversion.
Good Luck!
