Introduction
This is an updated version of t
he Analog Sound Sensor. Analog Sound
Sensor is typically used in
detecting the loudness in ambient, the Arduino can co
llect its output signal by
imitating the input
interface. You may use it to make some funny
interactive works such as a voice operated switch.
As one of our new version of br
eakout boards, we have improved the
analog sound sensor in below:
Wide voltage range from 3.3V to 5V
Standard assembling structure (two 3mm holes
with multiple of 5cm as interval)
Easily recognitive interf
aces of sensors ("A" for analog and "D" for digital)
Icons to simplely illustrate sensor function
High quality connector
Immersion gold surface
Specification

SampleCode
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);
}
Result
Open the Serial monitor, Baud rate: 9600.
