DIY Rain Detector Clothesline

📘 Project Overview

Ever forgotten your clothes outside and then it started to rain? This fun DIY Rain Detector Clothesline Using a Micro Servo lets you build a smart mini clothesline that moves when it starts to rain—using a rain sensor and a micro servo motor.

It’s a simple and creative way to learn about electronics, sensors, and Arduino programming. Great for science fairs or STEM classes!

🧠 What It Does

When rain is detected, a micro servo motor rotates, pulling a small clothesline arm (or blocking rain with a cover). It’s a basic automation system that uses sensors and code to respond to weather.

🧰 Materials Needed

🧱 Circuit Connections

Rain Sensor

• VCC → 5V on Arduino

• GND → GND on Arduino

• DO → Pin 7 on Arduino

Micro Servo

• Red wire (VCC) → 5V on Arduino

• Brown wire (GND) → GND

• Orange wire (Signal) → Pin 9

💻 Arduino Code

Upload this code using the Arduino IDE:

🔧 Assembly Tips

• Use cardboard or plastic to create a small clothesline or arm that the servo can move.

• Ensure the servo isn’t overloaded—this is a demonstration model.

• You can place the rain sensor on top of the project or outside a window with wires running in.

📚 What You’ll Learn

• How sensors work

• Basics of servo motor control

• Simple Arduino coding

• How to automate real-world problems

🧪 Extra Ideas

• Add a buzzer to beep when it rains

• Use an LCD screen to display status

• Build a waterproof mini cover for clothes using the servo

🎓 Conclusion

This Rain Detector Clothesline with a Micro Servo is a fun, educational, and creative project. You’ll learn electronics, programming, and automation while solving a real-world problem in a small model format—perfect for school presentations!
