#95507 Hi there,

As the title already mentions, my question is, could be the Built-In LED Brightness controlled on D1 mini board?
If yes, how?

Thank you for the answers and suggestions,

Kind regards,

#95509 Half the brightness:
Code: Select allvoid setup() {
  pinMode(LED_BUILTIN, OUTPUT); // <==== LED_BUILTIN should be set automatically to GPIO2 when the correct board is selected
  analogWrite(LED_BUILTIN, 127); // <==== change the second value [0...255] to set the brightness
