Build an RGB Colour Mixer with Arduino Uno — A Complete Beginner's Kit for Learning PWM and Colour Mixing

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

Create a dynamic colour mixer that lets you dial in any shade by turning three knobs. As your first RGB LED project, you’ll wire three potentiometers to control the red, green, and blue channels of an LED, watching it blend into vivid colours right before your eyes. No prior electronics experience needed—all parts are pre-tested and the step-by-step AI companion guides you through every connection.

What You'll Build

You’ll assemble a working circuit on a breadboard that mixes red, green, and blue brightness levels to produce any colour of the rainbow. With three smooth-turn potentiometers, you can fine-tune each channel independently and see the RGB LED respond instantly. It’s a satisfying project that turns simple components into a real-time colour tool.

What You'll Learn

• Generate PWM signals on Arduino pins to dim and brighten LEDs
• Read analog values from potentiometers using analogRead()
• Mix red, green, and blue light channels to create millions of colours
• Troubleshoot breadboard circuits and identify loose connections
