1.The circuit consists of a triode multivibrator driving two groups of LEDs to flash alternately. When the LED gyro is rotated, the vibration switch is turned on and the circuit works. Due to the phenomenon of visual retention, the pattern is left.

2.The working principle of the circuit: when the battery is installed, the vibration switch S1 is turned off. When the gyro is rotated, due to the centrifugal effect, the vibration switch S1 is turned on and the circuit works.ย

3.The working principle of the multivibrator is that when the power is turned on, the transistors Q1 and Q2 should be turned on first. Due to the difference of components, only one is turned on first, and then the two transistors in the circuit are turned on and off in turn, and the cycle Glow, so there will be multiple dashed patterns.
