10pcs KY-037 4pin Voice Sound Detection Sensor Module Microphone Transmitter Smart Robot Car

Features:

 

- For sound detection module has two outputs:

- There is a mounting screw hole 3mm

- The use 5v DC power supply

- With analog output

- High sensitive microphone and high sensitivity

- A power indicator light

- The comparator output is light

 

Specifications:

 

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

{digital Write(Led,LOW)}}

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); }
