This project demonstrates a simple and effective home automation system that allows users to control a light using voice commands via a smartphone. The system uses an HC-05 Bluetooth module, and a relay to switch a light ON or OFF based on voice inputs received through an Android phone.The core idea is to enable wireless and hands-free control of household lighting using Bluetooth communication and voice recognition apps. Voice commands such as "light on" or "light off" are converted into text by the Android app and transmitted to the HC-05 module. This project promotes the use of assistive technology and is ideal for elderly or physically challenged individuals, as it simplifies interaction with electrical appliances without requiring physical switches.
