Flash electronic spinning top — a traditional top updated with precision electronics for stable, clear LED patterns and readable text when spun. Key benefits Stable, repeatable displays: a Hall IC senses the magnet on every rotation and feeds that signal to the microcontroller, ensuring patterns and characters appear at the same point each spin. Precise LED control: a single-chip microcomputer sequences and times 12 light-emitting diodes, producing consistent patterns and legible text while the top rotates. Tradition meets technology: retains the familiar top form and play experience while adding modern visual effects for entertainment and demonstration. Main features Rotation sensing: Hall IC detects the magnet every turn and provides feedback to the microcontroller for synchronized display timing. LED control: single-chip microcomputer drives 12 LEDs; both the flash duration and the flashing sequence are controlled by the MCU. Pattern and text display: when the top rotates, the coordinated LED sequence forms the intended pattern and text for clear visual output. Design concept: a flash electronic top that preserves the classic top concept while integrating electronic display technology. Practical attributes Function: spinning top with magnet-sensing rotation feedback and MCU-controlled LED display. Performance: accurate synchronization between rotation and LED timing yields stable, repeatable patterns and characters. Form factor: traditional spinning top design combined with embedded electronic components for handheld use. Compatibility: built around a Hall IC + magnet sensing system and a single-chip microcontroller controlling 12 LEDs. Use scenarios Home entertainment: create eye-catching visual effects at parties, family gatherings, or casual play. Educational demos: demonstrate Hall-effect sensing, microcontroller control, persistence of vision, and basic electronics in a hands-on STEM activity. Gifts and collectibles: a modern take on a classic toy for enthusiasts who appreciate both tradition and simple electronic design. Technical summary Hall IC senses magnet on each rotation and feeds the signal back to the microcontroller for timing. Single-chip microcomputer controls 12 LEDs; flashing time and sequence are fully managed by the MCU. Result: corresponding patterns and text appear reliably while the electronic gyroscope (flash electronic top) spins, combining traditional form with modern electronic functionality.
