Story

Hey Friends...

In this Project I made a Sound Sensor at home.

The factory made sound sensors are very expensive so I have decided to buy components and make it at home.

This sound sensor I made at home works accurate.

You can use it in making a lot of projects like clap switch, room lights using sound sensor, VU light meter etc.

Steps to make this Project:

1. Gather all components as shown in circuit diagram of sound sensor.

2. Solder them on Zeroboard.

3. Or you can make a PCB and etch it then solder all of them.

4. After soldering all components run a test code using Arduino.

5. Connect Vcc to +5v

6. Connect GND to GND.

7. Connect Analog out pin of sensor to A2 of Arduino.

Check it...

Adjust the sensitivity according to your need.

Your homemade sound sensor is done...

If you like this project respect it.

Give me suggestions so I can improve it or any feedback you want to give to my YouTube channel.

Also you can give me suggestions on "What I made next project.?"

const int ledpin=13; // ledpin and soundpin are not changed throughout the process
const int soundpin=A2;
const int threshold=200; // sets threshold value for sound sensor
void setup() {
Serial.begin(9600);
pinMode(ledpin,OUTPUT);
pinMode(soundpin,INPUT);
}
void loop() {
int soundsens=analogRead(soundpin); // reads analog data from sound sensor
if (soundsens>=threshold) {
digitalWrite(ledpin,HIGH); //turns led on
delay(3000);
}
else{
digitalWrite(ledpin,LOW);
}
