Colour Sensor Fruit Sorter Kit — Fun Introduction to Light Sensing

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

With this kit, your child will build a real working circuit that can tell red apples from green apples — using just light and simple components. As they hold a red object near the sensor, a red LED lights up; a green object lights a green LED. It’s a magical first step into the world of electronics and sensing.

What You'll Build

Your child will assemble a circuit on a breadboard that uses two light-dependent resistors (LDRs) to detect colour differences. The finished sorter flashes a red LED when a red-coloured fruit or toy is placed in front, and a green LED for green items. It’s a hands-on tool to explore how sensors work in real life — from automatic doors to smartphone screens.

What You'll Learn

• How light sensors (LDRs) work and why resistance changes with brightness
• How to use a transistor as a switch to control LEDs
• Basic breadboarding and circuit construction without soldering
• Real-world application of colour detection in sorting machines
