Rainbow Knight Rider LEDs Variant 13 Kit with Arduino Uno + LED
Arduino Rainbow Knight Rider Kit – Build a Shifting Rainbow LED Scanner
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform any surface into a dynamic art installation with a sweeping rainbow scanner. This kit lets you build a Knight Rider‑style LED light that uses individually addressable WS2812B LEDs to create a back‑and‑forth chase effect – and every pass shifts the entire colour spectrum, producing an ever‑changing multicolour glow that’s both fascinating to watch and deeply satisfying to build.
What You'll Build
You’ll assemble a complete breadboard circuit that powers an 8‑LED WS2812B strip from an Arduino Uno. Once you upload the code, the LEDs sweep smoothly left and right in the classic scanner motion, but instead of a single red light you’ll see a smooth rainbow trail that evolves with each sweep. The finished project makes a captivating desk light, a wall‑mounted display piece, or a unique Diwali decoration that you created yourself.
What You'll Learn
- Program an Arduino to control individually addressable WS2812B LEDs using the FastLED library
- Understand how serial data and precise timing create per‑LED RGB colour commands
- Implement a Knight Rider back‑and‑forth pattern with a shifting hue offset that generates a rainbow trail
- Build a stable breadboard circuit with power‑conditioning components (capacitors and resistor) for noise‑free LED performance

Who This Kit Is For
Ideal for school students (CBSE Class 6–10) looking for a hands‑on electronics project, and a popular choice for ATL Tinkering Lab activities. Young makers aged 8 and up will enjoy building a vibrant light display that doubles as a science exhibition centerpiece or a unique Diwali decoration. Parents and educators can confidently guide children through the build using the included AI companion, making it a perfect first Arduino project.
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?
Simply scan the QR code included in the box to access your AI build companion, trained on this exact project. You can also reach our team on WhatsApp for immediate step‑by‑step guidance.
Do I need any prior coding or electronics experience?
No, this kit is designed for absolute beginners. The companion guides you through wiring and coding, and the sketch is provided. An adult can assist with the initial setup for younger builders.
Can I modify the light pattern or colours?
Absolutely. Once the basic scanner is working, you can experiment with the Arduino code to change rainbow speed, swap colour palettes, or even add more LED strips (additional strips not included) to create longer trails.
Is this kit suitable for a Diwali school project?
Yes, many students use it as a festive light decoration that demonstrates programmable electronics. It plugs directly into a wall socket, is safe for indoor display, and makes a standout exhibit at any school event.
