Virtual Controller

This project simulates a virtual relay and bulb system, controllable via HTTP requests in real-time. It integrates WebSockets for instant status updates, a PHP server for command processing, and a C-based virtual controller for simulation.

---

Features

• Real-time control and status updates using WebSockets
• PHP server processes commands (ON/OFF) via HTTP.
• Exposes the server to the internet using ngrok.
• Automates setup with shell scripts.

Setup Instructions

1. Install Requirements

• PHP
• GCC
• ngrok
• Composer (for dependency management)

2. Prepare Files

• Place all files in a single directory.

3. Install composer

composer install

4. Compile the C Program

gcc virtual_controller.c -o virtual_controller

---

How to Run

1. Start WebSocket Server

php server.php

• Starts the WebSocket server for real-time updates.

2. Start the Server and ngrok

./run_server.sh

• The PHP server and ngrok will start.

3. Expose the Server using ngrok

ngrok http 8080

• Use the provided public URL for external access.

4. Run the Virtual Controller

./run_system.sh

• Starts the virtual controller in sync with the server.

5. Test the System

• Use the ngrok public URL to send commands:

https://<your-ngrok-url>/controller.php?cmd=ON
https://<your-ngrok-url>/controller.php?cmd=OFF

• Check the output in the terminal for relay and bulb states.

Conclusion

This project simulates a virtual relay and bulb system that you control via HTTP requests. It integrates a PHP server, a C-based virtual controller, and uses ngrok for external accessibility. It's lightweight, cost-free, and sets the foundation for more advanced projects like integration or hardware control. 🚀 With everything automated through scripts, you can focus on experimenting and building new features. This project is perfect for learning system integration and handling real-time commands.
