I apologise if this seems like a really simple question, but I’m struggling to get the on-board LED to light up (using the usual digitalWrite(LEDPin,HIGH) etc with LEDPin set to 25. Worse than that (!), I can’t actually find the LED on the board (mainly because it is so small and won’t light up).
Is there something else I need to do besides setting the pinMode(LedPin,OUTPUT) and then using digitalWrite ?
Thank You !!
