~ LED4 composition. Gyro during rotation, due to centrifugal force, centrifugal switch Sl is turned on, the power is directly applied to four light-emitting diodes to emit light. At the same time ICl also powered buzzer BL emit the sound of music. Centrifugal switch S available elastic metal piece made several adjustments and the need to achieve better results. In addition, since the gyro is a rotating body motion, the overall balance is very important. Therefore, the layout of the printed circuit board not only pay attention symmetrical, taking into account the balance of weight in the vertical direction.
