### Project 12 A Flying Balloon

**1.Description**

When we throw a balloon to the height, it will rise slowly and turn around in the sky with the wind then slowly fall. When the balloon falls above our heads, touch it with a finger, then it will fly into the sky again.

In this project, there is a vibration tilt module, which can detect vibration and tilt. By using its characteristics, we can achieve the above interactive effect.

**2.Vibration Tilt Module Introduction**

![](media/image-20251208140338370.png)

The keyestudio vibration tilt module can be used to detect vibration and tilt. The SW-200D vibration switch element adopted on this module is a ball type tilt induction unidirectional trigger switch, one end of which is gold-plated(trigger end), the other is silver-plated (conductive end). 

When the module is in the horizontal position or inclined to the conductive end (silver-plated), the switch element is in OFF state and the signal end outputs a high level. When the module is tilted to the trigger terminal (gold-plated), the switch element is ON state, and the signal terminal outputs a low level.

When the angle of the conductive end (silver-plated) is lower than 10 ° horizontally and the module is shaken by external force, so the trigger end (gold-plated) will be in a short-time ON state, which makes the module detect vibration.
