SOUND DETECTOR MODULE FOR ARDUINO / FUNDUINO

For sound detection module has two outputs:
1. AO, analog output, the microphone real-time output voltage signal
2. DO, when the sound intensity reaches a certain threshold, the signal high and low expenditure

3mm hole screw mount

5V DC power supply

Analog output

Output threshold LED indicator

High sensitivity microphone

Power indicator light

Digital comparator output

Example code: Digital output

int Led = 13 ;// define LED Interface
int buttonpin = 3; // define D0 Sensor Interface
int val = 0;// define numeric variables val

void setup ()
{
pinMode (Led, OUTPUT) ;// define LED as output interface
pinMode (buttonpin, INPUT) ;// output interface D0 is defined sensor
}

void loop ()
{
val = digitalRead(buttonpin);// digital interface will be assigned a value of pin 3 to read val
if (val == HIGH) // When the sound detection module detects a signal, LED flashes
{
digitalWrite (Led, HIGH);
}
else
{
digitalWrite (Led, LOW);
}
}

Sample code: Analog outputs

int sensorPin = A0; // select the input pin for the potentiometer
int ledPin = 13; // select the pin for the LED
int sensorValue = 0; // variable to store the value coming from the sensor

void setup ()
{
pinMode (ledPin, OUTPUT);
Serial.begin (9600);
}
void loop ()
{
sensorValue = analogRead (sensorPin);
digitalWrite (ledPin, HIGH);
delay (sensorValue);
digitalWrite (ledPin, LOW);
delay (sensorValue);
Serial.println (sensorValue, DEC);
}
