I was following a tutorial regarding some new Hall sensors. After trying out a few changes in the code, the arduino software stopped uploading to the board. The code which was already on the Nano also isn't running anymore (I know this because a LED should light up when I pull a particular pin to GND).
After inspecting the Nano, here is what I observe:
- In Arduino software, after compiling the code, it's stuck on 'Uploading'.
- When uploading, the TX led blinks a few times briefly then stays off.
- No burned components or traces visible (at least to me, I haven't had much experience identifying these)
- My laptop still recognizes the Nano
- Doesn't upload on any other USB ports either
- When plugged in USB port, the PWR led lights up, but sketch doesn't seem to be running. Same thing with a 5V power bank.
- Pin Vcc to Pin Gnd reads 5.1V
- Weirdest thing: All GPIO except pin 13 have a small voltage of about 1,18 to 1,3V, it fluctuates between these values but it's the same for all pins. For pin 13 it reads about 0.57V.
Does anyone know what might be possible faulty or burned? I'm hoping if possible I can repair it myself
