Use of Microphone Module

In this article I will talk about the mic module with the arduino.You can practice with several microphone module.There are usually one per module 4.He writes the names on p. 5V Vcc pin plugs eat GND GND pin. The other two pins AO and DO pins are made of the connection pin number defined in the code section. A0 pin to analog, the DO pin is defined as the input pin reading digitally.

LED application volume is now the reference will blink for a second.

Connection pins:

Microphone module >>>>Arduino

AO____________________A0

DO____________________D2

VCC __________________ 5V

GND__________________ GND

Led >>>>>>Arduino

Anode_____D13

Cathode___ GND

// Robimek - Robotic Systems - 2016

const int DO_pin = 2;

const int AO_pin = 0;

int ses;

int led = 13;

void setup()

{

pinMode(DO_pin, INPUT);

pinMode(led, OUTPUT);

Serial.begin(9600);

}

void loop()

{

if (ses > 35)

{

digitalWrite(led, HIGH);

delay(1000);

digitalWrite(led, LOW);

}

ses = analogRead(AO_pin);

Serial.print(digitalRead(DO_pin));

Serial.print("-");

Serial.println(analogRead(AO_pin));

}
