I am trying to burn bootloader on Arduino UNO using MEGA2560 as the programmer, I followed the steps stated here but still get the error below:

         Double check connections and try again, or use -F to override
         this check.


avrdude done.  Thank you.

Note: The Arduino UNO stopped responding when I mistakenly short-circuited a connection, I mistakenly passed 12v to one of the header pins of sensor shield mounted on the board.

  • You note about short circuiting needs more explanation. Depending on what you did the device may be damaged. – jwh20 Dec 15 '20 at 13:34
  • Clearly, however, the MEGA is not communicating with the Uno. Please share how you have this hooked up. – jwh20 Dec 15 '20 at 13:34
  • @jwh20 I have included a connection diagram to the question. – Ruby Dec 15 '20 at 14:01

Based on this:

There are no I/O pins on the Arduino that are 12V tolerant. You have almost certainly "fried" your Uno board. It's possible the only casualty is the ATMega chip itself and replacements are available from a number of sources or you can purchase a "raw" one from an electronics reseller and use your programmer setup above to burn your own boot loader.

It's also quite likely that your sensor board is damaged as well.

From the Microchip datasheet:

You want something like this:

Adafruit Pre-programmed ATMega168p

Buy several, accidents happen!

    If it's any consolation, I've put 30VDC onto a pin of a Arduino Leonardo, just being sloppy with leads on a table. Strangely, it "worked" after that, though not the GPIO pin. But, it was rather hot and bothered about it and so untrustworthy thereafter; I mean it ran code, but you could fry an egg on it while it was doing so. I replaced the chip on it and now it's fine. It is entirely possible that only the AVR on your UNO is dead and with some work may be replaced. If it's a DIP based UNO as pictured, this is comparatively easy. – timemage Dec 15 '20 at 15:31

    Anyone who has experimented with electronics for any length of time has experience "smoke". I've lost track of how many expensive chips I've fried due to one oversight or another. – jwh20 Dec 15 '20 at 15:35
  • Or an Adafruit Pre-programmed ATMega328P rather. – timemage Dec 15 '20 at 19:54
