  • Description:
    For sound detection module has two outputs:
    1. AO, analog output, real-time output voltage signal of the microphone
    2. DO, when the sound intensity reaches a certain threshold, the output high and low signal
    Module features:
    1. there is a mounting screw hole 3mm
    2. the use 5v DC power supply
    3. with analog output
    4. there are threshold level output flip
    5. high sensitive microphone and high sensitivity.
    6. a power indicator light
    7. the comparator output is light
    Digital Output:
    int Led=13;//define LED interface
    int buttonpin=3 //Define D0 Sensor Interface
    int val;//define numeric variables val
    void setup()
    {pinMode(Led,OUTPUT);// Define LED as output interface
    pinMode(buttonpin,INPUT);//Define D0 Sensor as output Interface}
    (void loop)
    {val=digitalRead(buttonpin);//digital interface will be assigned a value of 3 to read val
    if(val==HIGH)//When the light sensor detects a signal is interrupted, LED flashes
    {digitalWrite(Led,HIGH)}else
    {digitalWrite(Led,LOW)}
    2. Analog Output:
    int sensorPin = A5; // 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);}
