This repository contains the source code and documentation for creating a simple sound alarm system using a sound sensor, Arduino, a speaker with an SD card module, an SD card, and jumper cables.

This project uses a sound sensor to control an LED with an Arduino. The LED lights up when the sound sensor detects noise above a certain threshold, making it a fun way to create sound-reactive ...

The sound sensor module will capture the sound using the onboard microphone and will give an amplified signal at the output. The frequency of this signal will then be calculated using an Arduino ...
