Sound Warning

This is Warning device When the sound exceeds the set level. The KY-037 is a voice receiver. And exported with ISD-1820 and BUZZER. The ISD-1820 is a voice recorder and plays if configured to match KY-037 and Set KY-037 to analog because analogue is a measurement that can measure the sound, which is different from the digital values can be measured only 0 and 1.

Steps

Step 1

Let's check the sound value. If the sound turns on, the LED will turn on.

Step 2

Add the buzzer and check the sound value together. If the sound turns on

Step 3

Add the sound recorder with check the sound value. If the sound turns on,the buzzer and recorder will turn on.

Step 4

Type code.

Step 5

Add the LED SWITCH 3 PRONG

Step 6

Complete arranging the components.

Code

Sound warning

int sensorPin = A0;    
int sensorValue = 0;     
int song = 2;         
int SOUT = 11;
int PLAYE = 9;

void setup()
{
  pinMode (sensorValue,INPUT);    
  pinMode (song,OUTPUT);          
  pinMode (SOUT, INPUT);
  Serial.begin(9600);
}

void loop()
{
  sensorValue = analogRead(sensorPin);    
  Serial.println(sensorValue);
  delay(1000);    
  int ret = digitalRead(SOUT);

if (sensorValue > 500)   
  {
    tone(song,500,300);
    Serial.println("--------------> PIR");
    digitalWrite(PLAYE, 1);
    delay(5000);
    digitalWrite(PLAYE, 0);
    noTone(song);             
    delay(3000);
  }
}
