C-M-01-28 – VOICE SOUND DETECTION SENSOR
Voice Sound Detection Sensor Module for official Arduino
boards.
boards.
- For sound detection module has two outputs:
- There is a mounting screw hole 3mm
- Uses 5v DC power supply
- With analog output
- High sensitive microphone and high sensitivity amplifier
- A power indicator LED
- The comparator output is a LED
Here’s a simple sketch for testing:
int Led=13;//define LED interface
int buttonpin=3 //Define D0 Sensor Interface
int val;//define numeric variables val
Â
void setup()
{pinMode(Led OUTPUT);// Define LED as output interface
 pinMode(buttonpin INPUT);//Define D0 Sensor as output Interface }
Â
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)}
Â
 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);}
Â
 void loop()Â
{sensorValue = analogRead(sensorPin);
  digitalWrite(ledPin HIGH);
  delay(sensorValue);
  digitalWrite(ledPin LOW);
  delay(sensorValue);
  Serial.println(sensorValue DEC); }
