Topic: Broken Arduino Uno? (Read 555 times) previous topic - next topic


Hi all,
So a while ago I fried my arduino uno's ATmega328 chip (I think that's what happened but now im not so sure) by accidentally letting a 12 wire slip on to one of the Atmega328's pins, frying it and my computer's USB controller :~. So recently I have gotten around to repacing the ATmega328 chip but after putting it in the built in LED on pin 13 blinks slowly then gradually blinks faster till it stops and windows says that the device malfunctioned. Does anybody know what this might mean??


12V will damage the microcontroller, and probably more. Also the logic chip, the usb-to-serial chip, perhaps a power regulator and maybe a capacitor. The Arduino Uno uses a ATmega chip for the usb-to-serial, if your computer was damaged, that chip was certainly damaged. That would result not in just one broken ATmega chip on you Uno board, but two.


Crap, so a new board is needed?
Thanks for your help
