Overview
The Sound sensor module is a simple microphone based on a opamp LM358 to amplify the sound strength of the environment like door knocks and etc loud enough to be picked up by a microcontroller's Analog to Digital converter. The value of output can be adjusted by the potentiometer.
Applications
- Simple microphone
- Sound detection
Connection Diagram
Here is the guide illustrates how to connect an Arduino to the sound sensor. The following is a table describing which pins on the Arduino should be connected to the pins on the sound sensor:
VCC <-------> VCC GND <-------> GND S <-------> Analog 0
Examples
void setup()
{
Serial.begin(9600); // open serial port, set the baud rate to 9600 bps
}
void loop()
{
int val;
val=analogRead(0); //connect mic sensor to Analog 0
Serial.println(val,DEC);//print the sound value to serial
delay(100);
}
