ATL Colour Mixing Light Lab Kit
ATL Colour Mixing Light Lab Kit – Master Additive Colour Mixing with RGB LEDs and Potentiometers
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn three potentiometer knobs and watch a single RGB LED shift through every colour of the rainbow — red, green, blue, cyan, magenta, yellow, and white. This kit transforms abstract colour theory into a tangible, hands-on experiment that aligns with CBSE and ATL curriculum goals. Perfect for classroom demonstrations or individual student projects, the ATL Colour Mixing Light Lab Kit makes learning about light and electronics immediate and unforgettable.
What You'll Build
You'll build a working additive colour mixer on a breadboard. Three potentiometers independently control the brightness of the red, green, and blue channels of an RGB LED. By adjusting the knobs, you can create any colour of light, directly demonstrating how screens and displays produce colour. The circuit is solderless, so you can rebuild it repeatedly for multiple classes or sessions.
What You'll Learn
- How red, green, and blue light combine to produce secondary colours (cyan, magenta, yellow) and white
- How potentiometers work as voltage dividers to control LED brightness without a microcontroller
- Basic breadboard wiring and circuit prototyping skills
- Ohm’s law in practice — using resistors to limit current through each LED colour

Who This Kit Is For
This kit is ideal for CBSE Class 9–10 students exploring light in physics, ATL Tinkering Lab sessions, and STEM clubs. B.Tech 1st-year students can use it for basic electronics lab work, while school teachers will find it a ready-to-use classroom demonstration tool for additive colour mixing. It’s also a popular choice for Smart India Hackathon junior tracks and science exhibition projects.
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?
Scan the QR code to chat with our AI companion trained on the ATL Colour Mixing Light Lab kit, or send a WhatsApp message to our support team for quick troubleshooting.
Can I use this kit for a CBSE practical exam project?
Yes, the circuit demonstrates Ohm’s law, voltage division, and additive colour mixing, which align with Class 9–12 physics curriculum. It's a compact, neatly presented project for viva and internal assessment.
Do I need soldering or prior electronics experience?
No soldering required — the kit uses a half breadboard and pre-cut wires. The step-by-step AI guide is designed for first-time builders aged 10 and up.
Can multiple students use the same kit in a classroom?
Yes, the solderless construction allows quick disassembly and rebuilding. One kit can support multiple lab periods, and the AI companion resets for each new builder.
RGB LED controlled by three potentiometers — students mix primary light colours and observe secondary colour formation.
