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

- Mon Nov 07, 2022 7:55 am #95508 It's possible to fade the built-in LED of Wimos D1. https://github.com/wemos/D1_mini_Exampl ... e/Fade.ino

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
}

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
