Powered by the classic NE555 timer IC and CD4017 decade counter, this 3V circuit kit lights up 10 LEDs in sequence around a circle. Press the button, watch the LEDs chase and gradually slow down — then see which one lights up last. A perfect introduction to practical circuit assembly, soldering skills, and fundamental electronics concepts.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003ePlease note:\u003c\/strong\u003e This kit is designed for electronics enthusiasts with basic soldering and circuit experience. All components are quality-checked before shipment; however, successful assembly depends on the builder's skill level. Please read all instructions carefully before beginning.\u003c\/p\u003e\n\n\u003ch3\u003eHow It Works\u003c\/h3\u003e\n\u003cp\u003eWhen the push button is pressed, the 10 LEDs illuminate one after another in a rotating sequence. The cycling speed gradually decreases until the light stops on a single LED — just like a spinning lucky wheel or electronic dice. It can be used as a number-guessing game, a random selector, or simply as a fun circuit-building project.\u003c\/p\u003e\n\n\u003ch3\u003eKit Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMain ICs:\u003c\/strong\u003e NE555 Timer + CD4017 Decade Counter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Supply:\u003c\/strong\u003e 3V DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePCB Board Size:\u003c\/strong\u003e 58 × 58 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLED Count:\u003c\/strong\u003e 10 LEDs arranged in a circle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAssembly Type:\u003c\/strong\u003e Through-hole soldering (DIY)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e Made in Mainland China\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat's Great About This Kit?\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e🎯 \u003cstrong\u003eHands-On Learning\u003c\/strong\u003e – Perfect for students, hobbyists, and educators exploring real circuit design\u003c\/li\u003e\n  \u003cli\u003e🔧 \u003cstrong\u003eSoldering Practice\u003c\/strong\u003e – Great for practicing through-hole component soldering techniques\u003c\/li\u003e\n  \u003cli\u003e💡 \u003cstrong\u003eClassic IC Design\u003c\/strong\u003e – Learn how the NE555 timer and CD4017 counter work together in a real application\u003c\/li\u003e\n  \u003cli\u003e🎲 \u003cstrong\u003eInteractive \u0026amp; Fun\u003c\/strong\u003e – Functions as an electronic dice, lucky spinner, or random number selector\u003c\/li\u003e\n  \u003cli\u003e📐 \u003cstrong\u003eCompact Form Factor\u003c\/strong\u003e – Small 58×58mm PCB is easy to manage and display\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWho Is This For?\u003c\/h3\u003e\n\u003cp\u003eThis kit is ideal for electronics students, STEM hobbyists, makers, and educators looking for a practical, engaging soldering project.
