Rainbow LED Color Mixer Kit – Press Buttons, Blend Colours – A Beginner Light Mixing Project for Kids

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

Every press of a button adds a splash of red, green, or blue light to a tiny mixing chamber — and suddenly, white, yellow, cyan, magenta, and every shade in between appear. This kit turns an abstract science concept into a glowing, hands-on experiment that young makers can hold in their palms. No computer, no code, just a breadboard, three buttons, and three RGB LEDs that unlock the secret behind every screen, stage light, and smartphone display.

What You'll Build

You’ll assemble a handheld colour mixer on a breadboard powered by a 9V battery. Press any combination of the three push buttons to blend red, green, and blue light directly in front of you. The result is a tiny light show that teaches how every colour on a screen is made — and you get to decide the recipe every time.

What You'll Learn

• How red, green, and blue light combine to make white, yellow, cyan, magenta, and countless other shades
• Building a circuit on a breadboard without any soldering
• How push buttons control electric current through an LED
• Understanding common-cathode RGB LEDs and why resistors protect them
