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,
Viktor

It's possible to fade the built-in LED of Wimos D1. https://github.com/wemos/D1_mini_Exampl ... e/Fade.ino

Half the brightness:

Code: Select all

void 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
}
