Build a Colour-Sorting Automatic Pet Feeder with Arduino Uno & TCS3200 Sensor

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

Make mealtimes magical—this kit lets you build a responsive pet feeder that reads the colour of a treat and drops it into the matching bowl. Using the TCS3200 sensor and two SG90 servos, the system identifies red, green or blue objects, then a lifelike arm sorts them into separate bins. It’s the perfect weekend project for young makers, parents, and educators exploring real-world robotics.

What You'll Build

You’ll assemble a tabletop automatic feeder with a colour-detection chamber. When a colourful treat token is placed under the sensor, the Arduino reads its RGB value and commands the servo arm to tilt toward the correct bin. By the end, you’ll have a working machine that can feed your pet (or a toy pet) different “meals” based on colour—ideal for school science exhibitions, ATL tinkering labs, or playful home automation.

What You'll Learn

• Interface a TCS3200 colour sensor and calibrate it to distinguish red, green and blue objects
• Control two SG90 servo motors to build a mechanical sorting arm
• Write Arduino code that reads sensor data and triggers precise movements
• Assemble circuits on a breadboard and manage power with a 9V battery
