1const int buzzer=9;
2int potpin=0;
3int button=3;
4int buttonState1=0;
5  int val=0;
6void setup() {
7  // put your setup code here, to run once:
8pinMode(buzzer,OUTPUT);
9Serial.begin(9600);
10pinMode(button,INPUT);
11}
12
13void  loop() {
14  // put your main code here, to run repeatedly:
15buttonState1 = digitalRead(button);
16val=analogRead(potpin);
17Serial.println(val);
18tone(buzzer,val);
19if(buttonState1==HIGH){
20  tone(buzzer,200);
21  delay(20);
22  noTone(buzzer);
23}
24
25}

const int buzzer=9;
int potpin=0;
int button=3;
int buttonState1=0;
  int val=0;
void setup() {
  // put your setup code here, to run once:
pinMode(buzzer,OUTPUT);
Serial.begin(9600);
pinMode(button,INPUT);
}

void  loop() {
  // put your main code here, to run repeatedly:
buttonState1 = digitalRead(button);
val=analogRead(potpin);
Serial.println(val);
tone(buzzer,val);
if(buttonState1==HIGH){
  tone(buzzer,200);
  delay(20);
  noTone(buzzer);
}
