Introduction

Octopus Electronic Bricks, you can use them build electronics projects just as easy as piling bricks. By using Octopus electronic bricks, you may connect Arduino/Freaduino compatible boards easily with various digital, analog and I2C/Uart interfaces. These the breadboard-less firm connection are prepared to extensive modules like poteniometers, sensors, relays, servos…even buttons, just plug and play.

Octopus Sound Sensoris a sensor module based on MIC sound sensing element . Sound Sensor is particularly sensitive to sound intensity,and it can be used to detect ambient sound level, but it can not identify the size of sound and the specific sound frequencies. It is available to make voice switches and other works. 3 pins electronic building block interface: input5V - GND, S for detection pin

Feature

  • Operating voltage:DC 5.0V
  • Adjustable sensitivity (shown in blue digital potentiometer adjustment)
  • With signal LED (if the signal output, the LED will be on)
  • Output type: Digital switching output 0-1(If detect sound,output “1”, and the signal LED will be on )

Programming

Includes important code snippet. Demo code like :

<syntaxhighlight lang="php">

const int SensorPin = 9; // the number of the Sensor pin const int ledPin = 13; // the number of the led pin

// variables will change: int SensorState = 0; // variable for reading the Sensor status

void setup() {

 // initialize the led pin as an output:
 pinMode(ledPin, OUTPUT);      
 // initialize the Sensor pin as an input:
 pinMode(SensorPin, INPUT);     

}

void loop(){

 // read the state of the Sensor value:
 SensorState = digitalRead(SensorPin);

 // check if the Sensor is close.
 // if it is, the SensorState is HIGH:
 if (SensorState == HIGH) {     
   // turn led on:    
   digitalWrite(ledPin, HIGH);  
   delay(200);
 } 
 else {
   // turn led off:
   digitalWrite(ledPin, LOW); 
   delay(200);
 }

} </syntaxhighlight>
