Smart Washing Line Retractor Kit - Build an Arduino-Powered Rain-Responsive Model

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Give your model house or school project a real automated system. This kit lets you build a miniature washing line that retracts clothes the moment rain starts - no need to rush outdoors. Using a rain sensor, an Arduino Uno, and a servo motor, you'll create a working prototype that mimics the logic of smart home devices. It's a hands-on way to understand how sensors talk to microcontrollers and how everyday problems can be solved with simple electronics.

What You'll Build

A fully functional model of an automatic washing line retractor. Place a damp cloth or a few drops of water on the rain sensor and watch the servo pull the line indoors. Adjust the sensitivity to respond even to light drizzle. The project runs on a 9V battery, making it portable and safe for young makers. Once built, you'll have a self-contained demo that showcases home automation in action.

What You'll Learn

• How a rain sensor detects moisture through changes in electrical resistance
• Programming an Arduino Uno to read analog sensor values and set thresholds
• Controlling a servo motor for precise, repeatable movement
• Assembling a complete sensor-actuator circuit on a breadboard without soldering

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is ideal for young learners aged 5-15 exploring STEM at home, CBSE Class 11-12 students tackling automation projects, and ATL Tinkering Lab participants building working sensor-based models. B.Tech ECE/EEE freshers will find it a gentle introduction to embedded systems, while parents and educators get a ready-made tool to teach cause-and-effect logic and coding. Even if you've never written a line of code, the AI companion makes the build straightforward.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
