Circuit Instruction:

When the battery is installed, the vibration switch S1 is disconnected, so the circuit does not work.

When rotating the spinning top, due to centrifugal left and right, the vibration switch S1 is turned on, and the circuit works.

The working principle of the multivibrator circuit is that when the power is turned on, the two transistors Q1 and Q2 will compete to be turned on first, but due to the difference of components, only one of the transistors will be turned on first.

Then the two transistors in the circuit are turned on and off in turn, and the two light-emitting diodes keep emitting light in cycles. When the top is rotated, a straight line will appear on the lit LED. Since the lamps are staggered and every two lamps are alternately lit, a pattern in the shape of a plurality of dotted lines appears.
