Arduino based Smart  Watch

So here we fetch some information from an Android mobile phone by using an android application and then send this information to OLED display by using Bluetooth Module and Arduino Pro Mini. Android smartphone already has inbuilt Bluetooth to send the data and at receiving end we have used Bluetooth module HC-06 with Arduino. Bluetooth module HC-05 can also be used in place of HC-06.
