Electronic Brick - Sound Sensor-Microphone Brick

This brick includes a high sensible microphone, it can be used to as a sound sensor or a microphone input for your project.

Overview

What is an electronic brick? An electronic brick is an electronic module which can be assembled like Lego bricks simply by plugging in and pulling out. Compared to traditional universal boards and circuit modules assembled with various electronic components, electronic brick has standardized interfaces, plug and play, simplifying construction of prototype circuit on one’s own. There are many types of electronic bricks, and we provide more than twenty types with different functions including buttons, sensors, Bluetooth modules, etc, whose functions cover from sensor to motor drive, from Ethernet to wireless communication via Bluetooth, and so on. We will continue to add more types to meet the various needs of different projects.

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

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);
}
