Sound Sensor/Microphone Brick

Sound Sensor/Microphone Brick

Electronic brick of microphone 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.

Features

1. Plug and Play, easy to use.Compatible with the mainstream 2.54 interfaces and 4-Pin Grove interfaces in the market.

2. With use of M4 standard fixed holes, compatible with M4-standard kits such as Lego and Makeblock

Specifications

PCB Size 33.0mm X 14.0mm X 1.6mm
Working voltage 5V DC
Operating voltage 5V DC
Compatible interfaces 2.54 3-pin interface and 4-pin Grove interface(1)

Note 1:  S for digital output port , V and G for voltage at the common collector and ground respectively

Sensitivity   -  -50  -  dB

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.

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