# ☔ Smart Cloth Line Control System
> An Arduino-driven retractable clothesline system that protects clothes from rain automatically.
---
## 📖 Description
This project monitors a **water sensor** to detect raindrops.
* When rain is detected, the system activates a **motor** for **2 seconds** to retract the clothesline under a protective roof.
* Once the sensor is dry (rain stops), the motor runs again for **2 seconds** to extend the line back outside.

## ⚙️ Hardware Setup
* **Arduino UNO** (or compatible)
* **Water Sensor Module**
* **DC Motor** + Driver (e.g., L298N)
* **Power supply** (matching motor requirements)
* **Clothesline mechanism** with retractable pulley
---
## 🚀 Installation & Usage
1. **Open** `Smart_Drayer.ino` in the Arduino IDE.
2. **Connect** the water sensor to an analog pin and the motor driver to digital pins.
3. **Select** your board & port under **Tools**.
4. **Upload** the sketch.
5. **Test** by simulating raindrops on the sensor; observe retraction and extension.

## 🔧 Configuration
Adjust these `#define` settings at the top of `Smart_Drayer.ino`:
```cpp
#define SENSOR_PIN A0 // Water sensor analog input
#define MOTOR_PIN1 9 // Motor driver IN1
#define MOTOR_PIN2 10 // Motor driver IN2
#define RETRACT_DURATION 2000 // Retract time in milliseconds
#define EXTEND_DURATION 2000 // Extend time in milliseconds
#define THRESHOLD 500 // Sensor threshold for rain detection
```
Modify the `THRESHOLD` value to calibrate sensitivity, and motor pins/times as needed.
---
## 🛠️ Operation Flow
1. **Monitor** sensor analog value continuously.
2. **If** value > `THRESHOLD` (rain detected):
* Activate motor to retract for `RETRACT_DURATION`
3. **Else if** value ≤ `THRESHOLD` (dry):
* Activate motor to extend for `EXTEND_DURATION`
4. **Loop** indefinitely.
