IR Remote Controlled Light and Fan Project Using Arduino

IR Remote Controlled Light and Fan Automation Using Arduino Nano

This IR Remote Controlled Light and Fan Automation project is a smart, beginner-friendly home automation system created using Arduino Nano. Designed especially for students in Bangladesh, this project allows you to control an AC light and a DC fan using a standard TV remote. When button "1" on the remote is pressed, an AC bulb (not included) turns on. When button "2" is pressed, a small DC fan is activated. This hands-on science project is ideal for school exhibitions, college presentations, and technical competitions. It is available at Bigyan Project, your trusted destination for science and robotics projects in Bangladesh.

Features

• IR remote-based wireless control system
• Real-life demonstration of home automation
• Includes TV remote for user interaction
• Arduino Nano programming with preloaded code
• Dual device control: one AC load and one DC load
• Compact and safe relay-based switching

Applications / Use Cases

• School and college science projects
• Home automation demonstration models
• Basic robotics and electronics learning
• Arduino and microcontroller practical projects
• Science fairs and innovation competitions

User Guide / How to Use

• Connect a mobile charger (not included) via the TP4056 module
• Use the provided TV remote
• Press button "1" to turn on the light (bulb not included)
• Press button "2" to turn on the fan (included with mini DC motor)
• Make sure the IR receiver is aligned with the remote for proper operation

Frequently Asked Questions (FAQs)

• Is the AC bulb included? No, only the holder is included
• Can I use any TV remote? Yes, most remotes with standard IR signal will work
• Is it safe to connect to AC power? Yes, relays are opto-isolated and switching is handled securely
• Is this a DIY kit or ready-made? This is a fully assembled and tested project from Bigyan Project
• Can I use this with smart home setups? This is a basic automation demo and not Wi-Fi enabled

Challenges and Considerations

• IR signal needs direct line of sight to function correctly
• Bulb must be connected safely with appropriate precautions
• Power source must match TP4056 requirements (5V mobile charger recommended)
• Ensure capacitor polarity is maintained during usage

Compatibility

• Compatible with most universal and standard TV remotes
• Can be integrated into larger Arduino projects with slight code modifications
• Works with 5V USB mobile chargers (via TP4056 module)

Future Enhancement Options

• Upgrade to Wi-Fi or Bluetooth control using ESP8266 or HC-05 modules
• Expand to control more devices using additional relays
• Add LCD display to show device status
• Include sound or motion sensors for advanced automation

Benefits

• Perfect for hands-on learning and real-world electronics understanding
• Enhances knowledge of automation, relays, and microcontrollers
• Encourages creativity in science fair and robotics competitions
• Fully functional and tested product from Bigyan Project
