Buzzer Push Button Example

// constants won't change. They're used here to set pin numbers:
const int buttonPin = 2; // the number of the pushbutton pin
const int button1Pin = 3; // the number of the pushbutton pin
const int ledPin = 13; // the number of the LED pin
const int buzzerPin = 9; // buzzer to arduino pin 9

// variables will change:
int buttonState = 0; // variable for reading the pushbutton status
int button1State = 0; // variable for reading the pushbutton status

void setup() {
  // initialize the LED pin as an output:
  pinMode(ledPin, OUTPUT);
  // initialize the pushbutton pin as an input:
  pinMode(buttonPin, INPUT);
  pinMode(button1Pin, INPUT);

  // initialize the pushbutton pin as an input:
  pinMode(buzzerPin, OUTPUT);

}

void loop() {
  // read the state of the pushbutton value:
  buttonState = digitalRead(buttonPin);
  button1State = digitalRead(button1Pin);

  // check if the pushbutton is pressed. If it is, the buttonState is HIGH:
  if (buttonState == HIGH) {
    // turn LED on:
    digitalWrite(ledPin, HIGH);
  } else {
    // turn LED off:
    digitalWrite(ledPin, LOW);
  }
  
  
  // check if the other pushbutton is pressed. If it is, the buttonState is HIGH:
  if (button1State == HIGH) {
    // turn Buzzer on:
    tone(buzzerPin, 1000);
  } else {
    // turn Buzzer off:
    noTone(buzzerPin); // Stop sound
  }
