Today is soldered my project together but unfortunately there was a small passage wich shot-circuited the 5V to gnd. Fixing the soldering work was a small job but the arduino is no longer working. It still gives power but it does no longer execute the uploaded program and on my mac i get the error 500 (“programmer not responding”) when i try to reupload (also on windows btw). I think that the atmega is burned (can it be this?) and is it repairable? There was no smoke or anything like that but the atmega is now producing heat (which wasn’t the case before).
And i thougth that the arduino was able to withstand a small short circuit.
