Kit name: LED Light Kit B

Kit model: HBL-22

Working voltage: DC4--6V

When the battery is loaded, the vibration switch S1 is off, so the circuit does not work. When the spinning gyro

At that time, due to the centrifugal effect, the vibration switch S1 is turned on, the circuit works, and the multivibrator circuit works.

The principle is that when the power is turned on, two triodes Q1 and Q2 will be turned on first, but because of the transistor

A difference, only one pipe is the first to conduct. Then, the two triodes in the circuit conduct in turn.

On and off, the two light-emitting diodes emit light circularly. When the gyro is rotated, the bright LED

There will be a straight line, because the lights are staggered and every two lights turn on alternately, so

A number of dotted patterns appear.
