DIY Vibration Alarm Kit w/ Sound & Light

The vibration alarm uses the principle of closed-circuit to complete the small electronic production of sound, light and electricity. When the small screw hung in the air is shaken, it will touch the metal ring at its upper end, and then the light-emitting diode will keep flashing, and the speaker will sound, which will act as an alarm.
