Hi @davidelflores7. Please try this experiment and then report back with the results:
- Connect your Arduino board to your computer with the USB cable.
- Press and release the reset button on your Arduino board quickly twice.
- If it is already open, close the Tools > Port menu in Arduino IDE.
- Open the Tools > Port menu in Arduino IDE.
Now please reply here on the forum thread with the answers to the following questions:
- Do you now see the "L" LED on the board next to the "5V" pin pulsing?
- Do you see a port for the board in the Tools > Port menu?
