Build practical electronics skills while creating a fun, interactive LED Fortune Wheel. This kit combines NE555 and CD4017 logic with a userfriendly PCB to teach soldering, basic circuit design, and circuit integration using safe lowvoltage power. Key benefits Handson learning: Practice soldering and component placement while seeing immediate visual results from the spinning LEDs. Clear circuit fundamentals: The design uses NE555 and CD4017 chips to demonstrate timing and counting principles in a simple, tangible project. Durable for practice: Prelabeled PCB with corrosionresistant pads, polarity markers, and fireproof, quality materials stands up to repeated soldering exercises. Easy activation and fun output: Start the sequence with a push button or by shaking the board; LEDs spin, race, and stop at random for game or experiment uses. Safe and compatible: Operates from 3V to 5V power sources, making it compatible with common battery packs and safe for classroom demonstrations. What it does Function: Produces a randomized spinning LED display that can be triggered by button press or motion. Circuit components: Built around NE555 timing chip and CD4017 decade counter to create the spinning and random stop behavior. Assembly features: PCB is prelabeled with component outlines, corrosionresistant pads, and clear polarity markings to simplify learning and reduce errors. Practical use scenarios Classroom soldering lab: Teach soldering technique, electronic component identification, and timing circuits in a single handson project for students aged 14 and up. Hobbyist project spinner: Add an interactive element to DIY games or party props that requires minimal power and simple controls. STEM demonstration: Use the random stop behavior to illustrate probability, timing, and digital counting in experiments or presentations. Notes for buyers Recommended age: 14 and up; adult supervision advised for firsttime builders. Power: Use a 3V to 5V supply for safe operation and easy integration into lowvoltage projects. Assembly tip: Follow the PCB markings for polarity and component placement to ensure reliable operation and effective practice. This kit provides a practical, lowrisk way to develop soldering and electronics fundamentals while producing a visible, interactive result suitable for classrooms, hobbyists, and STEM learning projects.
