When i connect my arduino nano to windows 10; the arduino nano is powered on (the "POW" led is on and not blinking; none of the others are on) but it doesn't show up on my computer. It used to but I think I may have shorted it.
Oddly, I get a measurement of 5V coming from digital pins 2,3,4 if connected through USB or 12V if I connect external power source to V_in. These are the pins that were on before what I believe was a short. Can someone tell me what is the component that is damage and whether it is possible to fix. Thanks!
