3pcs 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: 3 x KY-037 Voice Sound Detection Sensor Module
