Documented Code

Arduino UNO 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 Arduino UNO. The setup() function is where you initialize settings, and the loop() function runs continuously after the setup is complete. You can add your specific logic to read sensor data, control the buzzer, and manage the LED within these functions.
