Smart Automatic Window System using Arduino | LDR Sensor + Servo Motors

Описание: In this video, we build a Smart Automatic Window Opening System using Arduino Uno and an LDR sensor, where the window opens and closes automatically based on sunlight intensity.
This project demonstrates how real-world smart home automation works, using two servo motors — one for each window flap — to create smooth, realistic window movement.

The entire setup is built using a breadboard only, making it a low-cost, beginner-friendly, and school-safe Arduino project.
When sunlight falls on the LDR sensor, Arduino detects the increased light level and slowly opens the window.
As the sunlight reduces or is blocked, the system automatically closes the window smoothly, without any manual control.

This project clearly explains how sensors, conditional logic, and servo control are used in smart homes, greenhouses, and automated ventilation systems.

🔍 What You’ll Learn:
✔ How an LDR sensor detects sunlight
✔ Reading analog sensor values using Arduino
✔ Using threshold-based decision making
✔ Controlling servo motors smoothly
✔ Slow open & slow close automation logic
✔ Writing clean and structured Arduino code
✔ Basics of smart home & environmental automation

🧰 Components Required:
1 × Arduino Uno
1 × LDR (Light Dependent Resistor)
1 × 10K Resistor
2 × Servo Motors (for window flaps)
Breadboard
Jumper Wires
USB Cable for Arduino

⚙ Working Principle:
✔ LDR continuously senses sunlight intensity
✔ Arduino reads analog values from the LDR
✔ If light crosses the set threshold → window opens slowly
✔ If light drops below the threshold → window closes slowly
✔ Both servos move together for symmetric window motion
✔ Fully automatic system — no buttons or switches required

📌 Applications:
Smart home window automation
Greenhouse ventilation systems
Automatic sunlight control
Energy-efficient buildings
School & college Arduino demonstrations
