LED Colour Mixing Wheel Kit — Build a Spinning Disc That Mixes Colours with Light and Electronics

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

Watch red, green, and blue LEDs blur into yellow, cyan, and magenta as the disc spins. This kit transforms a simple circuit into a mesmerizing colour-mixing wonder — the first taste of how electronics and optics team up to create the colours on every screen.

What You'll Build

A sturdy cardboard disc carrying three sets of primary-colour LEDs, spun by a small motor at the press of a button. As the wheel whirs faster, your eyes blend the separate lights into completely new shades — exactly the same additive colour trick used in televisions, stage lighting, and phone displays. You'll hold a working model that explains a deep physics concept through pure hands-on play.

What You'll Learn

• Wire LEDs with current-limiting resistors to build a safe, reliable circuit
• Discover how our eyes and brain combine rapid light pulses into a single blended colour
• Connect a DC motor and push-button switch to control motion precisely
• Explore the additive colour wheel: red + green = yellow, red + blue = magenta, green + blue = cyan

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Perfect for curious kids aged 6-8 who love building things and asking “why?”. Ideal for CBSE Class 1–3 hands-on science activities, a first dip into electronics at ATL Tinkering Labs, or a joyful parent-child weekend project. If your young maker wants to see how light mixes and motors spin, this kit turns those questions into a glowing, twirling discovery.
