Pesfehhy Electronic DIY Kit LED Fingertip Gyro Manufacture DIY Soldering Kit Colorful Diode Electronic Training Set SMD Welding

In order to improve the stability of pattern and text, the circuit uses Hall IC to control the regular display of pattern, that is, for each rotation, Hall IC senses the magnet, then feeds back the model number to the single chip microcomputer, and uses button battery for power supply When the battery gyro is turned off, the MCU automatically enters low power consumption. When you the switch, you can turn on the LED. The gyroscope uses a single chip microcomputer to control the rotation of 12 light-emitting diodes, and the flashing time of each light-emitting diode The order of flashing is controlled by the single chip microcomputer. When the electronic gyro rotates, the corresponding pattern and text appear. It can rotate with the gyro rotating on the finger, display words and patterns, use 3 cr1220 button batteries in series to supply power, and supply it to the single chip microcomputer after stabilizing the voltage to 5V through the voltage stabilizing chip. With a power switch, the single chip microcomputer controls 24 patch LEDs to flash at high speed according to the font data, and make use of the visual persistence of human eyes Text or pattern is presented in the rotation range of 24 LEDs.
