I would like to do that if a checkbox is ticked, that then after a QR code scan the mobile phone vibrates if it is not ticked then it does not vibrate. Question: How does it work? Is that even possible with the TinyDB if so, how? If not, how too? With wich blocks?
How exactly does the TinyDB fit in here?
You can create a QR code with this amazing extension by @vknow360:

TinyDB should be used only if you want your app to remember user's settings
