Match Any Colour Instantly with Arduino & TCS34725 Sensor Kit
Build a Real-Time Colour Matching System with Arduino Uno & TCS34725 Sensor Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Colour is everywhere, but capturing it precisely and recreating it with light is a skill reserved for engineering labs-until now. This kit lets you build a handheld colour detector that reads any surface colour using the TCS34725 digital colour sensor and instantly reproduces it on an RGB LED, teaching you sensor integration, I2C communication, and PWM brightness control in a single, rewarding project.
What You'll Build
You'll assemble a portable colour-matching system: point the sensor at a surface-a leaf, a fabric swatch, a paint chip-and watch the RGB LED glow with the exact same hue and intensity. The build realises a fully functional colourimeter, ready to be embedded into robotic sorting projects, interactive art installations, or science fair demonstrations.
What You'll Learn
- Interface the TCS34725 RGB sensor via I2C with Arduino Uno
- Parse raw colour data and convert to 8-bit RGB values
- Map colour values to PWM duty cycles for precise LED colour mixing
- Implement a real-time feedback loop between sensor input and LED output

| Build support | Forums and scattered tutorials | AI companion trained on this exact project |
| Time to first working build | Days of debugging | Hours, with step-by-step guidance |
| Shipping coordination | Multiple sellers, multiple delays | One shipment from Bengaluru in 3-5 days |
Who This Kit Is For
CBSE Class 12 students tackling physics or computer science practicals will find colour sensing a brilliant data-acquisition experiment. B.Tech ECE/EEE undergraduates can use it to master I2C protocols and PWM control. ATL Tinkering Lab mentors and Smart India Hackathon teams prototyping automated sorting will appreciate the ready-to-use components and the real-time feedback loop that makes debugging intuitive.
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.
What if I get stuck during the build?
Open the QR code on the box to access your AI build companion, trained on this kit's wiring and code. If you need a human, WhatsApp us and a build engineer will reply within a few hours.
Can I use this to detect and classify multiple colours for a sorting machine?
Yes, the TCS34725 outputs precise RGB values; with simple threshold conditions in your Arduino code, you can program it to distinguish between red, green, blue, and custom-defined colours for sorting tasks.
Do I need prior coding experience to assemble this kit?
The kit includes a pre-written Arduino sketch with comments explaining each step. If you're new to coding, the AI companion will walk you through uploading it and modifying variables for your own colours.
What if the LED brightness doesn't match exactly-how do I calibrate?
Ambient light can affect sensor readings. The AI companion includes a calibration routine that samples ambient light and adjusts your colour mapping, ensuring the LED output remains accurate in different lighting conditions.
TCS34725 RGB sensor reads object colour and drives RGB LED to match detected colour in real time.
