The spinning top is a gadget that has been handed down from ancient times to today. The flash electronic top is a novel electronic toy that combines modern technology and tradition. It not only retains the primitive connotation of the top, but also reflects the attractive charm of modern electronic technology.
The gyro uses a single chip microcomputer to control 12 light-emitting diodes to flash in turn. The flashing time of each LED and the flashing sequence are controlled by the single-chip microcomputer. When the electronic gyroscope rotates, the corresponding pattern and text will appear.
In order to improve the stability of patterns and characters, Shenlu adopts Hall IC to control the regular display of the pattern, that is, every time it rotates, the Hall IC senses the magnet, and then the model is fed back to the microcontroller.
The coin-cell battery is used for power supply, and the microcontroller automatically enters low power consumption when the battery gyro is turned off. When the switch is pressed, the LED is turned on.
