In this article, I will show you how to interface a sound sensor module in Arduino. Using this module, you can capture sound as input to control other parts of your device. Integrating this into your projects can greatly improve the functionality of your device.

Sound Module Interfacing in Arduino: Steps in Creating the Device
Here are the steps in interfacing the sound module in Arduino.

1 Gathering the Components:
The first thing to do is to collect the hardware components for the Arduino device.
Arduino Uno
Sound Sensor Module

2 Connecting the Components:
Connect the components to the Arduino Uno. Please refer to the wiring diagram below.

3 Coding the Arduino:
The third step is about coding the Arduino device.

4 Upload the Sketch:
The final step is uploading the sketch to the Arduino.

Sound Module Interfacing in Arduino: Detailed Explanation
Step 1: Gathering the Components
To start off, this project will have two parts: the Arduino Device and the Program. The first thing to do is to collect the hardware components and make the device. To do that, you will be needing the following:

Quantity Components
1 Arduino Uno
1 Sound sensor module

Step 2: Connecting the Arduino Components
Now you are ready to connect the components to the Arduino Uno. Connect the power and the ground pins to 5V and GND. Next is to connect the VRX and VRY to A0 and A1. Lastly, connect SW pin to a digital pin.

In the diagram, the sound sensor module is connected to 5V pin of the Arduino. For the output pin, connect it to digital pin 2. if you have the 4-pin variant, use the digital pin of the module.

Step 3: The Arduino Code
Copy the code below to a new sketch in the Arduino IDE. Once done, you can upload it to the Arduino Uno.

Step 4: Upload the sketch
After you successfully upload the sketch, open the serial monitor of the Arduino. Here you can see that the module detects a clapping sound.

So there you have it! Sound Sensor Module Interfacing in Arduino. This project is intimidating at first but you will see that it is fairly easy to do. You can combine this with other Arduino projects and build an awesome system!
