Broken Arduino? Answered
Few days ago I was making arduino project which involved using power supply with 12v (musical floppies). I had uno connected to my laptop and I was connecting power supply to floppy which arduino was supposed to control, but I plugged wire in wrong socket. Computer and power supply shut down immediately. I checked later and it appears that I put 12v straight into ground that was also connected to arduino. And later when I tried to upload something on board I got error 0x00 not in sync. 13 led turns on when connected, but board dodn't respond to reset. But it appears on computer so it's not completely fried I think. After some research I bought usbasp programator to try burning new bootloader, but after connecting it always say target doesnt answer. check connections. I did that (didn't checked with multimeter yet) but Im pretty sure its wired correctly. Any ideas? And if not is buying new chip (atmega328-p) going to solve problem?
