Code: const int trigPin = 4; const int echoPin = 5; const int buzzerPin = 8; void setup() { pinMode(trigPin, OUTPUT); pinMode(echoPin, INPUT); pinMode(buzzerPin, OUTPUT); } void loop() { digitalWrite(trigPin, LOW); delayMicroseconds(5); digitalWrite(trigPin, HIGH); delayMicroseconds(10); digitalWrite(trigPin, LOW); int duration = pulseIn(echoPin, HIGH); delay(50); int distance = duration / 29.1; if (distance < 20) { digitalWrite(buzzerPin, HIGH); } else { digitalWrite(buzzerPin, LOW); } }

Thank you. I dont have much information about that, but according to me you can use the 12v buzzer used in bikes and cars. also, if you are using that then make sure to give 12v power supply to arduino through the input jack for 12v adapter given on arduino.

Pulsein was not declared in this scope this error come program

I have checked the code from my end and there is no issue but still if you are getting the error then you can recheck if this line is written as it is in your code "int duration = pulseIn(echoPin, HIGH);". If still you are getting the error then try updating your arduino software.
