In this project we are going to build a Dog Barking Security Alarm using Arduino Nano, PIR Motion Sensor, and Dog Barking Sound Module.

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 ...

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.

In this Arduino IR sensor module tutorial we are explaining how to connect IR sensor module with Arduino Uno and write the code to get the IR motion sensor working.
