So I am planning to participate in some challenge. I should make something like this:
Project to locate item, the thing I make with Arduino should be connected to phone via Bluetooth and attached to item I want to locate, and when it gets out of range, phone starts to vibrate or to produce some sound until user click something on mobile. It should also produce sound if I want to find it, I click on mobile app or something.
Can I get any suggestion on what should I buy and how to do it?
That is one question.
The other is if I want to show last location of item, how could I make that? (This question isn't really important, but I would do it if I could finish my project on time, I'm focused on first one).
If anyone wants to help further please contact me.
