Home Automation with Digital Door Lock System
This project aims to build a digital door locking system that controls home appliances via Bluetooth. It includes components like Helium board, Arduino Uno board, and HC05 Bluetooth module. Users input a password through a keyboard, allowing control over appliances only when the door is unlocked. The system also features a light sensor for room light control and potential modifications for enhanced functionality.

HOME AUTOMATION MADE BY: PRABAL BHATNAGAR HIMALI GOEL SHIKHA VERMA T.S.S.S SRINIVAS
INTRODUCTION AIM: To build a digital door locking system with the capability to control most of the home appliances via a bluetooth device to control all the system using a mobile app. To Control the room lights according to the presence of light in the room using a light sensor. The basic control of the appliances will be allowed only when the door is unlocked. In a situation when the digital lock is asserted(i.e. door is locked), all appliances will remain switched off.
COMPONENTS : HELIUM BOARD ARDUINO UNO BOARD DIGITAL I/O BOARD HC05 BLUETOOTH MODULE LCD DISPLAY
IMPLEMENTATION PASSWORD IS ENTERED THROUGH A KEYBOARD BINARY PASSWORD IS CONVERTED INTO DECIMAL THE COMPARATOR CHECKS THE PASSWORD ON PRESSING ENTER, LED1 LIGHTS UP FOR A CORRECT PASSWORD AND LED2 FOR A WRONG PASSWORD THREE CONSECUTIVE WRONG PASSWORDS CAUSE THE BUZZER TO BLOW ONCE THE DOOR IS SUCCESSFULLY UNLOCKED,THE USER IS GIVEN CONTROL OF HOME APPLIANCES TO ENHANCE THE USE OF APPLIANCES, FOR EG LIGHT, A PHOTO DETECTOR HAS BEEN USED THE USER IS ASKED FOR CONFIRMATION FOR TURNING ON THE LIGHT IN CASE THE LIGHT SENSOR DETECTS ENOUGH LIGHT IN THE ROOM
MODIFICATION POSSIBILITIES: COMMUNITCATION THROUGH WIFI MODULE TO TURN SOME APPLIANCES SUCH AS AC ON PRIOR TO ARRIVAL AT HOME TEMPERATURE SENSORS TO CONTROL SPEED OF FAN/HEATER TO IMPROVE HOME LOCKING SYSTEM, WE CAN SEND AN SMS TO THE HOUSE OWNER ON THE ENTRY OF THREE WRONG PASSWORDS
