My arduino uno was working fine from the first day. I used it for christmas light decorations and after that my uno stopped working. The problem is the computer doesn't recognize it. The lights on the uno are working and the micro controller is also working. It,s not either the usb cable or the computer because i tried using other cables and computers. It,s more likely I burnt the usb interface chip. Is there any way that i can upload a code to this board?
picture?
You can use a second Uno or a Nano as an ISP programmer. Do you have a second controller?

Yeah I have another uno. I’ll try this.
if you connect this to PC it must appear new device in Device Manager
Program something simple that blinks pin 13 LED and writes some serial data to the serial monitor. If you toasted your USB interface if should blink but not write to the monitor. Their wouldn't be a COM port available
I checked that before. It doesn’t appear anywhere
COM port doesn’t appear
