KY-037 4pin Voice Sound Detection Sensor Module Microphone Transmitter Smart Robot Car for Arduino

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); }
 
Package Included:
 
1 x KY-037  Voice Sound Detection Sensor Module
