i'm using a 5v pro mini and i accidently touched the vcc with the - of the 9v battery, while + was connected to the raw pin. now the pro mini works fine when connected to the usb power supply, but connected to the battery i only get a dim red power led and it doesn't work anymore. is there any way of saving my arduino?
Edit: Recommendations removed... Nevermind...
the board still works great with usb power connected to the vcc. so maybe there is something damaged behind the raw pin. can i work around that?
Come on guys he said it works fine when powered from the USB so that would not indicate that the processor chip or the LED needs replacement. Problem is most likely with the voltage regulator chip and/or it's supporting components.
