I am a beginner to Arduino and I have a question about my "Aruino Nano RP2040" which may have a defect?
When I first connected USB voltage, the on-board LEDs begin blinking in orange and green. This seems to me like a kind of boot procedure.
But after a lot of playing with connecting and disconnecting, now the on-board LEDs are no longer blinking when I connect voltage. The green LED is now always lit and I am not able to connect the board with my Notebook.
I wonder if the board can have a kind of hardware defect now? Can anybody explain what the Blinking and not Blinking LEDs on connecting voltage mean?
Thanks for help.
