Who has by no means left their telephone in a single place and realized too late that they’ve misplaced it? On this undertaking we’ll search for an answer to the issue; every time you’re too far-off out of your telephone, “Don’t Lose Me” will blink and whistle, in addition to your telephone will play an annoying sound (or a music of your selection).
A Bluetooth connection is established between the telephone and “Don’t Lose Me” (through the HC05 module). Your telephone is consistently sending knowledge to an Arduino Nano. When the connection is interrupted it’s for two causes: both you’re too removed from the cell or you have got pressed the crimson button. In each circumstances the consequence is similar, Arduino receives no knowledge and begins blinking and whistling, your telephone detects that the information it’s sending has no receiver and consequently it can play an alarm.
