Usage

<syntaxhighlight lang="c">

  1. include <math.h>

const int buzzerPin=3; //Connect the Buzzer module to Pin3, Digital 3 float thresholdVoltage= 1.84; //The treshold for which the Buzzer should sound. void setup() {

  Serial.begin(9600);                //Start the Serial connection
 pinMode(buzzerPin,OUTPUT);            //Set the LED on Digital 12 as an OUTPUT

} void loop() {

float sensorValue; float sensorVoltage; sensorValue = analogRead(A2); sensorVoltage =(sensorValue/1024)*5.0;

if(sensorVoltage<thresholdVoltage)

 {
   digitalWrite(buzzerPin,HIGH);
 }
 else
 {
 digitalWrite(buzzerPin,LOW);
 }
sensorVoltage = sensorVoltage/101*1000;

Serial.println("the output voltage is:");

Serial.print(sensorVoltage); Serial.println("mV"); delay(1000); }
