Device: Arduino Uno
I accidentally used terminal 13 as my ground terminal.
It worked for some time, and I did not notice the error.
Now I noticed that there are some problems with digital terminal 13.
I am unable to upload a sketch to the device now if there is something connected to 13.
And sometimes it provides a voltage even when output is not enabled on this terminal.
Other than that, If I stop using this pin everything else seems to work fine.
If I replace the Atmega chip will that solve this problem? or is the damage on the board?
Is this the correct replacement chip for the Arduino Uno?https://www.adafruit.com/products/123
