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

Description

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 interfaceint buttonpin=3 //Define D0 Sensor Interfaceint 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 valif(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 potentiometerint ledPin = 13; // select the pin for the LEDint 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: 10 x KY-037 Voice Sound Detection Sensor Module Please note that buyers are responsible for all additional fees, brokerage fees, , and es for importation into your country.
