Hello, yesterday i was experimenting with my arduino and i accidentally touched with 12V1.5A the digital pin 2 for a second on my Arduino Uno r3
the code that i was trying works but i cant send new code on my Arduino
i tried removing the atmega328 chip, shorter tx-rx pins and tried to send something on the serial monitor to get it back but nothing happens, the tx-rx led's are not working, i tried another atmega328 chip but still nothing
is the MEGA16U2 chip dead? also if i buy an arduino compatible board and switch the chips is there any chance that it will work?
(update) i tried now to upload the blink example with a cp2102 usb to serial and it worked, tried the pin2 with a led and that worked too
