• Arrange the speaker with pin 3 of the Arduino Mega 2560 V3.0 placed in the working area.
• Similarly, place the button on pin 2 of the microcontroller. The screen should look like the following image:

• Now, go to terminal mode from the leftmost and place the ground terminals with the components.
  

Now, connect all the components through the connecting wires. Here is the final circuit:

Now, it's time to add code to the simulation.

Code for Arduino Mega 2560 V3.0

• Start your Arduino IDE.
• Create a new project by going into sketch>new sketch.
• Delete the present code from the project.
• Paste the following code into the project:
  

const int buttonPin = 2;    // Pin connected to the button

const int speakerPin = 3;   // Pin connected to the speaker

int buttonState = 0;        // Variable to store the button state

boolean isPlaying = false;   // Variable to track whether the speaker is playing

void setup() {

  pinMode(buttonPin, INPUT);

  pinMode(speakerPin, OUTPUT);

}

void loop() {

  // Read the state of the button

  buttonState = digitalRead(buttonPin);

  // Check if the button is pressed

  if (buttonState == HIGH) {

    // Toggle the playing state

    isPlaying = !isPlaying;

    // If playing, start the speaker

    if (isPlaying) {

      digitalWrite(speakerPin, HIGH);

    } else {

      // If not playing, stop the speaker

      digitalWrite(speakerPin, LOW);

    }

    // Add a small delay to debounce the button

    delay(200);

  }

}

• You can get the same code from the zip file you have downloaded from this tutorial. 

• Click on the "verify" button present on the above side of the code. 

• Once the loading is complete, click on the “upload” button present just at the side of the verify button. It will create a hex file in your system.

void setup() {

  // declaring pin 9 to be an output:

  pinMode(LED, OUTPUT);

}

void loop() {

  // setting the brightness of pin 9:

  analogWrite(led, brightness);

  // changing the brightness for next time through the loop:

  brightness = brightness + fadeAmount;

  // reversing the direction of the fading at the ends of the fade:

  if (brightness <= 0 || brightness >= 255) {

    fadeAmount = -fadeAmount;

  }

  // waiting for 30 milliseconds to see the dimming effect

  delay(50);

}
