Arduino Sound Detection Sensor

What you need:
1PCS Arduino UNO R3
1PCS Sound Detection Sensor
3P Female to Male Dupont Cable

Pin Outs:

Connection:

Code:

//Henry’s Bench

//Arduino Sound Detection Sensor Module

 

int soundDetectedPin = 10; // Use Pin 10 as our Input

int soundDetectedVal = HIGH; // This is where we record our Sound Measurement

boolean bAlarm = false;

 

unsigned long lastSoundDetectTime; // Record the time that we measured a sound

 

 

int soundAlarmTime = 500; // Number of milli seconds to keep the sound alarm high

 

 

void setup ()

{

Serial.begin(9600);

pinMode (soundDetectedPin, INPUT) ; // input from the Sound Detection Module

}

void loop ()

{

soundDetectedVal = digitalRead (soundDetectedPin) ; // read the sound alarm time

 

if (soundDetectedVal == LOW) // If we hear a sound

{

 

lastSoundDetectTime = millis(); // record the time of the sound alarm

// The following is so you don’t scroll on the output screen

if (!bAlarm){

Serial.println(“LOUD, LOUD”);

bAlarm = true;

}

}

else

{

if( (millis()-lastSoundDetectTime) > soundAlarmTime  &&  bAlarm){

Serial.println(“quiet”);

bAlarm = false;

}

}

}
