product description:
When the battery is installed, the vibration switch S1 is disconnected, so the circuit does not work. When the spinning top is turned on due to the centrifugal effect, the vibration switch S1 is turned on, the circuit works, and the working principle of the multivibrator circuit is that when the power is turned on, when the power is turned on, the two transistors Q1 and Q2 will compete to be turned on first. However, due to the difference of components, only one tube is turned on first. Then the two triodes in the circuit are turned on and off in turn, and the two light-emitting diodes continuously emit light. When the spinning top, the bright LED will appear a straight line, because the lights are arranged in a staggered arrangement, at the same time every two lights are alternately lit, so there are multiple dotted-shaped patterns.
