Code Documentation

Wemos D1 Mini Code

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This code is a basic template for the Wemos D1 Mini. The setup function is called once when the microcontroller starts, and the loop function runs continuously. You can add your specific logic to control the RGB LED and other components in these functions.
