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

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.
