Android Based Double Authentication Security System 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. 4X4 Keypad connected to Arduino digital pins. WORKING: Here we have to access door with double authentication. Initially we have to give password from Android Application. If password is correct then it allows us to next step. Otherwise buzzer sound will come and notification will come to Android Application. In next step we have two passwords, one password is for door open and second password is for door close. These passwords we have to give from 4×4 keypad. In this Android Double authentication security system project can see the all password status, message will be displayed on Android Application. Also this information displayed on 16X2 LCD display.
