enter image description hereI am new to arduino and robotic stuffs and I thought it would be a good idea to test circuits on my breadboard using arduino's R3 5V pin as power supply. The accident happened when I short circuited the things on the breadboard and after a while arduino gave off a nasty smell. The only part overheated on arduino was the left side of the micro-controller. After that I cant upload nor run code on arduino.

After I explained you my situation, can you imagine a potential problem?(e.g I mean is it a voltage regultor problem, a micro-controller faillure, both of them, or something else?)

Can I fix it?

(#1 - I know arduino boards are cheap. I just want to know if I can do anything with that.

#2 - No comments about the accident accepted.)

Thank's in advance.

Regarding the image, my vendor claims the arduino to be an exact copy of "open-source" arduino R3

If your power supply still works, there's a decent chance you can repair the board by replacing its microcontroller which is conveniently socketed.

it depends on your skills and the nature of the problem and how far you are willing to go to fix it.

I would first try to rule out a supply problem - very rarely a mcu will burn to the extent of giving off smells / overheat. So unplug the mcu and use a multimeter to measure its Vcc vs. GND pin voltage, test trace continuity, etc.

after that, plug in a new / known good chip and see if you could upload code to it.
