DIY NE555 CD4017 Running LED Flow Light Production Kit

Build your own mesmerizing running LED light display with this hands-on DIY electronic kit! Featuring the classic NE555 timer IC and CD4017 decade counter, this production suite creates a smooth, flowing LED light sequence that's perfect for electronics enthusiasts, students, hobbyists, and makers of all skill levels.

Why You'll Love This Kit

Engaging Build Experience: Assemble your own running LED flow light from scratch — a fantastic way to learn circuit design, SMD soldering, and IC-based timing circuits.
Classic IC Combination: Uses the widely studied NE555 timer (clock generator) paired with the CD4017 decade counter to drive LEDs in a sequential running pattern.
SMD Components Included: Each order includes SMD components for a compact, professional-looking finished board.
Multiple Quantity Options: Available in 1-piece, 5-piece, and 10-piece sets — ideal for classrooms, workshops, or bulk hobby projects.
3 Color Options: Choose from 3 LED color variants to customize your light display.
Customizable Design: Fully customizable to suit your project needs — adjust timing, LED count, and layout.
Great for Learning & Decor: Use it as a science/electronics learning project or as an eye-catching decorative light display once assembled.

How It Works

The NE555 timer IC generates a clock pulse signal, which feeds into the CD4017 decade counter IC. The CD4017 steps through its 10 output pins sequentially with each clock pulse, lighting up each LED in turn to create the classic "running light" or "chasing light" effect. It's a timeless beginner-to-intermediate electronics circuit that teaches real-world IC principles.
