Rainbow Knight Rider LEDs Kit with Arduino Uno + LED
Rainbow Knight Rider LED Sweep Kit – Arduino Uno Drives a Colour-Shifting LED Chase
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 an eight-LED strip sweep back and forth in the classic Knight Rider style, but with a twist — the colour flows through a full rainbow hue on every pass. This project turns simple code into a mesmerizing desktop light sculpture, teaching you how one data pin can orchestrate millions of colours with a WS2812B strip. Designed as a first step into addressable LEDs, the kit gives a stunning result that feels far more advanced than the beginner-level wiring and code involved.
What You'll Build
You'll assemble a self-contained LED display that runs a continuous rainbow Knight Rider animation the moment you power it up. The strip glides a moving dot left and right, and every return trip shifts the entire colour spectrum, so the effect never repeats exactly. It sits neatly on a breadboard, making it easy to show off at a school science exhibition, decorate a desk, or spark a child's interest in coding.
What You'll Learn
- Program an Arduino Uno to control a WS2812B LED strip using the FastLED library
- Create smooth colour transitions by manipulating the HSV colour space in code
- Use a capacitor and resistor to protect the LED strip from voltage spikes and ensure clean data signals
- Build a breadboard circuit that bundles power, ground, and a single data wire — a template for all future addressable LED projects

Who This Kit Is For
This kit is purpose-built for children aged 5–15 who are taking their first hands-on dive into electronics and coding. It aligns with the hands-on learning goals of ATL Tinkering Labs and CBSE school projects, giving a visually rewarding outcome in a single afternoon. It's also a favourite for hobby clubs, parent-child weekend builds, and demonstration tables at Smart India Hackathon junior events where a quick, colourful prototype is needed.
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 on the box to start a conversation with the AI companion, which walks through every connection and line of code. If you need a human touch, our WhatsApp support team responds within hours.
Do I need any coding experience to make this work?
None at all. We provide the complete, annotated code ready to upload to the Arduino Uno. You'll learn how to change the speed and colours by editing just two numbers, giving a gentle introduction to programming.
Is the power supply safe for a 5-year-old to use?
Yes, the 5V 1A adaptor is a regulated, low-voltage unit that plugs into a wall socket. The breadboard circuit keeps all connections accessible but insulated, and the current draw is well within safe limits for children handling the board under adult supervision.
Can I later expand this to more LEDs or a larger project?
Absolutely. The same wiring and code logic scale to longer WS2812B strips or rings. Once you have this base circuit on a breadboard, you can attach a strip with dozens or even hundreds of LEDs and adapt the code with minimal changes.
WS2812B 8 LED strip sweeps knight rider pattern with rainbow colour that shifts each pass.
