Bluetooth Based Password Control Door Lock Electronics Engineering Final Year Project

This project includes Bluetooth (HC-05) module, which is connected to Arduino through UART interface. Dc motor connected to Arduino digital pins through l293d H-Bridge.

WORKING:

Here we can control door from android Application. User has to install Application in his mobile. Here there are two password for door control. One is for door open and second one is for door close. For wrong password buzzer will be ON. Password status will displayed on 16X2 LCD display.
