Build a Working Traffic Light Sequence with Raspberry Pi Pico and MicroPython

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

Ever watched a traffic light cycle from red to green and wondered how that timing works? With this kit, you’ll program your own traffic light controller using a Raspberry Pi Pico, three coloured LEDs, and MicroPython. In just a couple of hours, you’ll see your code come to life as LEDs light up in perfect sequence — a real-world embedded systems concept stripped down to its essence.

What You'll Build

You’ll assemble three LEDs (red, yellow, green) on a breadboard, connect them to your Pico’s GPIO pins, and write a MicroPython script that cycles them exactly like a traffic signal. The result is a small but fully functional model that blinks with precise timing, ready to show off at a school exhibition or kickstart your journey into microcontroller programming.

What You'll Learn

• Write MicroPython code to control GPIO pins as digital outputs
• Use time delays (sleep) to sequence LED states accurately
• Wire LEDs with current‑limiting resistors on a breadboard safely
• Understand how timing logic underlies real‑world traffic light controllers

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Whether you’re a CBSE student from Class 6 onwards exploring ATL tinkering labs, a young innovator in a school STEM club, or a parent looking for a screen‑time‑to‑skill‑time activity, this kit delivers a satisfying first microcontroller project. B.Tech ECE freshers and diploma students will also find it a clean, practical introduction to GPIO control and MicroPython.

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.
