Description
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. 5v DC power supply
3. With analog output
4. there are threshold level output flip
5. high sensitive microphone and high sensitivity.
6. Power indicator light
7. comparator output is light
Digital Output:
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(button pin,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)}
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)
