Descriptions:


This module can be connected to the analog I / O port,
when speaking to the microphone, the analog value will be changed.
A recorder can be made by reading and saving the analog value.

DEMO:

Connect S port of electronic brick of microphone to A0 port of Arduino, and we will use the following program to read the analog value. When the value exceeds the threshold, the LED indicator will flash.


1 const int ledPin = 13; // the number of the LED pin
2 const int thresholdvalue=400; //The threshold to turn the led on
3 void setup() {
4 pinMode(ledPin, OUTPUT);
5 }
6 void loop() {
7 int sensorValue = analogRead(A0); //use A0 to read the electrical signal
8 if(sensorValue>thresholdvalue)
9 digitalWrite(ledPin,HIGH); //if the value read from A0 is larger than 400,then light the LED
10 delay(200);
11 digitalWrite(ledPin,LOW);
12 }
