Traffic Light Simulator Kit with Arduino Uno + LED
Build a Working Traffic Light Simulator with Arduino Uno – Beginner Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine building a miniature traffic light that cycles through red, yellow, and green just like the ones on your street. With this Arduino-based kit, you'll program the sequence yourself, learning the core concepts of microcontroller output and timing that underpin countless real-world automation systems. This project transforms abstract coding commands into a tangible, blinking display that instantly rewards your effort.
What You'll Build
You'll wire up three LEDs on a breadboard, connect them to an Arduino Uno, and write code that uses digitalWrite() to turn each LED on and off, and delay() to create the familiar red-yellow-green rhythm. The finished project is a fully operational traffic light simulator — a proud result you can demonstrate to family, classmates, or teachers, and a foundation for more complex Arduino creations.
What You'll Learn
- Control multiple LEDs in sequence using Arduino digital outputs
- Implement precise timing intervals with the delay() function
- Assemble a circuit on a breadboard with LEDs and current-limiting resistors
- Debug a looping program to create a continuous traffic light cycle

Who This Kit Is For
This kit is ideal for students in CBSE Class 6-10 exploring electronics, first-year B.Tech ECE/EEE students needing a hands-on project, participants in ATL Tinkering Lab activities, and hobbyists of any age who want to learn Arduino programming by creating something relatable. It's also a perfect entry point for Smart India Hackathon prep and NIT/IIT mini-project ideas.
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?
The AI companion, accessible via QR code, guides you step-by-step. If you need human help, WhatsApp our support team with a photo of your setup and we'll assist within hours.
Can I modify the code to change the light sequence?
Absolutely. The kit includes spare LEDs and resistors, so you can extend the circuit. The AI companion can suggest code tweaks for patterns like a pedestrian crossing signal or a blinking yellow caution light.
Is the Arduino Uno ready to use out of the box?
Yes, the genuine Arduino Uno comes with a bootloader pre-installed. You'll write and upload the traffic light code using the free Arduino IDE; the companion walks you through the one-time IDE setup and first upload.
What if a component is missing or damaged?
Compoden offers a 7-day free replacement for any manufacturing defect. Just WhatsApp or email a photo of the issue, and we'll ship a replacement from Bengaluru within 24 hours.
Three LEDs cycle red amber green like a traffic light using delay() and digitalWrite().
