💡 Light Scheduler

📝 Overview

A smart light scheduling system that allows users to set ON/OFF times via a web UI.
The schedule is sent over WebSocket → MQTT → Arduino, controlling an LED accordingly.

🛠️ Tech Stack

• Frontend: HTML, CSS, JavaScript (WebSocket client)
• Backend: Python (WebSocket server, MQTT publisher)
• IoT: Arduino (LED control), MQTT (Mosquitto broker)
• Protocol: WebSocket, MQTT, Serial

🚀 How to Run

1. Start MQTT Broker
   Run Mosquitto on localhost:1883.

2. Connect Arduino
   Upload the Arduino sketch and ensure it's on the correct serial port (e.g., COM3).

3. Run Subscriber
   python subscriber.py (receives MQTT messages, sends commands to Arduino)

4. Run WebSocket Server
   python backend.py (listens on ws://localhost:8765)

5. Open client.html
   In a browser to set the light ON/OFF schedule.

⚠️ Make sure you installed all python packages, by

python install -r requirements.txt

🕒 LED will toggle based on the scheduled times!
