Motorised Pet Door Kit with Arduino Uno: A Colour-Sorting Project for Young Makers

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

Does your pet’s toy box turn into a jumbled mess of red, green, and blue chaos? With this kit, you’ll build a motorised gate that automatically identifies a toy’s colour using a TCS3200 sensor and rotates a servo arm to drop it into the matching bin. It’s a fun, hands-on way to bring automation into your home while keeping your furry friend’s play area neat.

What You'll Build

A compact sorting station: a colour sensor scans the object placed in front, an Arduino Uno reads the data, and an SG90 servo moves a chute to the correct bin. Place it near your pet’s corner and watch red, green, and blue toys get organised without any manual work. The build introduces basic machine vision principles in a tangible, rewarding project.

What You'll Learn

• How a TCS3200 colour sensor detects red, green, and blue values from reflected light
• Programming Arduino Uno to read sensor output and map it to servo angles
• Wiring a breadboard circuit with LEDs, resistors, and a servo for real-world automation
• Testing and calibrating a colour-sorting system—debugging false reads and mechanical alignment

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11-12 students building physics or computer science practicals will appreciate the real-world sensor integration. B.Tech ECE/EEE freshers can use it as a quick embedded systems demo. ATL Tinkering Lab mentors find the colour-sorting concept ideal for introducing IoT basics, and parents of curious kids aged 5-15 get a ready-made, safe, and educational weekend project that needs no soldering.

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.
