Code Documentation

ESP32 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 ESP32 microcontroller. The setup function is called once when the microcontroller starts, and the loop function runs continuously. You can add your specific logic and functionality within these functions.
