100% brand new and high quality
For sound detection module has two outputs:
1. AO, analog output, real-time output voltage
signal of the microphone
2. DO, when the sound intensity reaches a
certain threshold, the output high and low
signal
Module features:
1. there is a mounting screw hole 3mm
2. the use 5v DC power supply
3. with analog output
4. there are threshold level output flip
5. high sensitive microphone and high
sensitivity.
6. a power indicator light
7. the comparator output is light
Digital Output：
int Led=13;//define LED as interface
int buttonpin=3 //Define D0 Sensor as 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
{
digitalWrite(Led,LOW)
}
}
2.Analog Output：
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);
}
