WELCOME TO NABAJYOTI'S GITHUB PAGE

The aim of this project is to make a password locking security door with alarm system. So that the system can give a alarm if anybody is at the door and it can be accessed by user using entering password .The user can change the password also of this system. User can run this system in automatic mode also.

REQUIRED COMPONENET FOR THIS PROJECT

1.ARDUINO

2.UlTRASONIC SENSOR

3.HC-05

4.SERVO MOTOR

5.MOBILE APP

The mobile app is made in MIT APP Inventor.

PROJECT PREVIEW

CIRCUIT DIAGRAM

Circuit diagram is given below . Hc-05 module is not not there.The Rx pin of Hc-05 will be connected to arduino Tx pin and Tx pin will be connected to Arduino Rx pin.Remaining circuit is same as diagram given below.

FUNCTION PREVIEW

The system work as suppose a person is arrived in front of door then it will give an alarm So that the user can notice then user will input password into app and if the password match the app will send signal to arduino then door will open vice versa which is a model made by servo motor in this project. A special option is there that automatic mode where user can give the command to door inputing password to open and close simulteneously if there is a person in front of door.It will be checked by ultrasonic sensor.There is a buzzer which give the alarm.
