Arduino Sound Detection Shusher

Making shure it's quiet

The Susher

This project was a bit different than usual. It was a fun little school projected that lasted for a couple days. We came up with this idea because our concentration skills were often challenged because of the noisy working area's at school.

The idea was, that when the noise level became to high, the device would pick it up and would play a very loud SHHHH sound. That way, everyone would shut up. This was accomplished by using a sound detector with an Arduino.

int Led = 13 ;// define LED Interface
int buttonpin = 3; // define D0 Sensor Interface
int val = 0;// define numeric variables val
void setup ()
  pinMode (Led, OUTPUT) ;// define LED as output interface
  pinMode (buttonpin, INPUT) ;// output interface D0 is defined sensor
void loop ()
  val = digitalRead(buttonpin);// digital interface will be assigned a value of pin 3 to read val
  if (val == HIGH) // When the sound detection module detects a signal, LED flashes
    digitalWrite (Led, HIGH);
    digitalWrite (Led, LOW);
