Microfon sensibilitate
[D05-E9]

7,00Ron

Modul : microfon

• 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  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(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); 
  }
