I fried my arduino. Can I upload code wirelessly? 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?
If the main MCU is still functioning fine then yes, sure you can.

The only caveat is that you may have to manually reset the Arduino at the right moment in order to enter the bootloader for programming.


Connect the bluetooth module to TX/RX/GND (TX->RX, RX->TX)
Configure the bluetooth module to work at the bootloader baud rate (115200 baud) - you may need to wire it to your PC to manage this part.
Connect a virtual COM port to it and program through that.
Press RESET just as it's about to run AVRDUDE in the IDE.
