Hi, i been using my arduino uno for a few weeks now. Working perfectly fine. I tried using a 12V wall converter to plug into my uno for a project I need. and now i cant upload anything. pin 13 led turns on but does not blink when i plug it into my computer. The green "on" light is on and everything. does this mean my uno is fried? If it was fried, wouldnt the arduino not turn on at all?
Also, does this mean it is not safe to plug in a 12V wall outlet converter to the arduino?
