Bluetooth is a wireless technology standard for exchanging data over short distances using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz from fixed and mobile devices.
The idea of our project exploit the benefit of these technologies to build a device that can be stick with personal things that we suffer from its loss. These will be done by using android, arduino, Bluetooth module and alarm unit.
Our device will be made from arduino, Bluetooth module, led and buzzer. So to communicate with these device we will programming an android application which can use in any smart phone to send some instructions to Bluetooth module using Bluetooth technology then the module in his role send these instruction to arduino so depend in receiving orders the device will be making a light or a sound so you can found your lost things easily.
