Project Idea:
The project is designed to provide a secure, easy-to-use remote door-opening system controlled through an Android application. It unlocks the door only when the correct password is entered via Bluetooth communication, ensuring security and convenience for authorized personnel.
 
Project Description:
This system uses an Android app with Bluetooth connectivity to control and unlock a door remotely. The authorized user enters a password on the app, which is transmitted to the Bluetooth module. These commands are received and processed by an 8051 microcontroller. If the password matches, the microcontroller activates the lock mechanism to open the door.
This solution is especially useful for security personnel or situations where frequent door access is needed without requiring manual effort. It also allows operation from a vehicle without exiting, making it safe and efficient.
