The Voice-Controlled Home Appliances project is a smart automation system that enables users to operate household devices such as lights, fans, and other electrical appliances using voice commands. The system is powered by a microcontroller (Arduino/ESP32) integrated with a voice recognition module or a smartphone app with Google Assistant/Alexa integration.

When a command like “Turn ON the light” is given, the voice signal is processed and transmitted to the Arduino, which then activates a relay module to switch the respective appliance ON/OFF. This project showcases the Internet of Things (IoT) concept, making daily life more convenient, energy-efficient, and user-friendly.

Parts Used:

1. Arduino UNO / NodeMCU / ESP32 – Microcontroller unit.
2. Voice Recognition Module / Google Assistant / Alexa – For capturing commands.
3. Bluetooth / Wi-Fi Module (HC-05 / ESP8266) – Wireless communication.
4. Relay Module (4/8 Channel) – Controls home appliances.
5. Smartphone with App / IoT Platform – User interface for voice input.
6. Power Supply (5V/12V Adaptor) – To power controller and relays.
7. Home Appliances (Fan, Light, TV, etc.) – Load devices.
8. Connecting Wires & Enclosure – For safe and portable setup.
