Ever wished your laundry could protect itself from sudden rain? 🌧️👕 The Smart Laundry Bot makes that possible! This DIY Arduino project automatically pulls back your clothesline when it detects raindrops, keeping your clothes safe and dry. With a rain sensor, servo motor, and Arduino Uno, you can turn a simple idea into a working smart home prototype.
This DIY Arduino project automatically retracts your clothesline when it detects raindrops, keeping your clothes safe and dry. What makes it stand out is its custom 3D-printed miniature house model, turning a simple build into a realistic smart home prototype.
By combining electronics, sensors, actuators, and 3D design, this project bridges the gap between learning and real-life application. Whether you’re a student, hobbyist, or DIY maker, the Smart Laundry Bot is an excellent way to explore automation, coding, and 3D prototyping while solving an everyday problem.
What You’ll Learn
By completing the Smart Laundry Bot project, you’ll gain skills in automation and Arduino.
- How to use a rain sensor to trigger automation.
- Practical applications of electronics for everyday chores.
- How servo motors can power moving mechanisms.
Why Build a Smart Laundry Bot?
The Smart Laundry Bot is more than just a clever household hack—it’s a 3D-printed automation project that brings smart home technology within reach. By building it, you’ll not only gain experience with sensors, coding, and actuators, but also learn how 3D printing can turn your idea into a functional prototype. This combination of electronics and 3D design makes the project more realistic, creative, and engaging.
It’s especially useful for students and DIY enthusiasts who want to explore how simple electronics can be applied to real-world problems while also practicing 3D design integration. Most importantly, it demonstrates how automation and 3D models can be used in everyday life—turning a basic clothesline into a responsive, weather-aware system inside a customized 3D-printed build.
If you’re interested in other servo-based weather projects, you can also check out the 3D Mini Rain Car Wiper. In the same way, it uses a servo motor to mimic real-world automation—this time, replicating the motion of car wipers when it rains.
What You Need
To build your Smart Laundry Bot, you’ll need these components.
- Servo MG90D 360 – moves the clothesline back and forth
- Rain Sensor – detects rain or water droplets
- Arduino Uno R3 – the brain of the system
- Jumper Wires – for connections
- Type B Cable
- Alkaline Battery AA
- Battery Holder 8 x AA
How It Works
The Smart Laundry Bot uses a simple sense → process → react cycle:
- Rain Detection: The rain sensor monitors for water droplets.
- Signal Processing: Once rain is detected, the Arduino processes the signal.
- Automatic Action: The servo motor immediately pulls back the clothesline to safety.
- Clear Weather: When the rain stops, the servo extends the clothesline back to let clothes dry in the sun.
This smart yet straightforward setup mimics the logic behind automated windows, greenhouse covers, and other smart weather systems.
