In this project, I built a smart home automation system using ESP32 and a 4-channel relay module. This setup allows you to control 4 AC lights wirelessly using your smartphone from anywhere using WiFi.

The ESP32 is connected to a relay board that switches 220V AC appliances safely, and the control is done through a mobile app interface. This project is simple, low-cost, and perfect for beginners who want to start with IoT and home automation.

⚡ Features:

Control multiple lights from phone 📱
Works over WiFi (no manual switch needed)
Safe AC load control using relays
Expandable for more devices

🛠️ Components Used:

ESP32 Dev Kit
4 Channel Relay Module
AC Bulbs (220V)
5V Power Supply
Jumper Wires

💡 This project can be upgraded by adding voice control, timers, or automation features.
