Modulo sensor sonido salida analoga y digital

• 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.
  　
• G connect to GND. "+" is connected with the positive. A0 connect to the analog signal. DO connect to digital signal.

　

• 1. 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);
  }
