Glowing/pulsing yellow LED?



  • Hello

    I have a strange problem, My sketch works for maybe half a day and then the yellow LED starts to show a glowing/pulsing light. It is connected to a 5V USB power supply. I don't know how to troubleshoot this since it take so long time for the problem to occur.

    I have enabled a watchdog functionality in the sketch, so why isn't that kicking in if there is any problems?

    It is a MKRNB 1500 board.

    It helps if you post a wiring diagram and a sketch.
