Video Demonstration

This project demonstrates a simple web-based control panel using an ESP8266 or ESP32.
It lets you wirelessly turn a relay module ON or OFF using a browser, no internet needed!

• The ESP8266/ESP32 creates a Wi-Fi Access Point with a custom SSID and password.
• A simple web server runs on port 80.
• The server displays an HTML interface with ON/OFF buttons.
• Clicking a button sends a GET request to toggle GPIO12 (D4 on ESP8266).

This project is for educational and experimental purposes only.

• Do not connect high-voltage mains power unless you are fully trained and aware of electrical safety.
• Improper use of relay modules or incorrect wiring can cause fire, electric shock, or damage to devices.
• Always use low-voltage testing before connecting mains appliances, and follow local safety regulations.
• The author is not responsible for any damage, injury, or loss caused by using this project. Always handle electronics safely and operate the device in a controlled environment..

⚠️ Use the NO (Normally Open) terminal of the relay for correct operation.
