So, I'm a complete arduino newbie. I left a live wire close to my arduino and part of it burnt (underneath the USB output). The LED that indicates power still turns on when I plug it into my computer, and a simple LED circuit on my breadboard, when hooked up to the arduino, still works. The only thing that's wrong is that my computer doesn't recognize the Arduino serial port any more, so I can't upload any code onto it.
I also own a bluetooth HC-05 module. Is there any way I could upload code onto my Arduino wirelessly, using that? Or am I better off just buying a new one?
