Something is SERIOUSLY wrong! No way should the device draw enough juice to set fire to components! Do NOT reconnect the device to your computer. There shouldn't be that much current - you could fry your computers board.Check and recheck your schematic, especially the alignment of the plugs etc Try uploading a photo.

First pin to AVCC Second (middle) to ground and third to controllerWhrong-middle pin can not be connected t0 ground--has to go to controller

I connected them the way you said but the same happend when i turned the pot to the left it started burning
