11. Why do you think bluetooth technology is not used in TV remotes and car locks?
Answers
Answer:
As smartphones have recently become one of the most popular devices worldwide, various convenient applications are being released. Now smartphones not only provide the ordinary internal processes such as dialing or receiving phone calls, sending text messages, and doing mobile banking wherever we are, but they also are beginning to control various other devices that are part of our lives. Through the smartphone using mobile applications, we can remotely control a variety of external devices such as TVs, projectors for presentations, computers, and even cars. This paper presents the design and implementation of a remote lock system using wireless communications. The remote lock system is a lock system that can be controlled remotely by a dedicated Android application. The main function of the Android smartphone is equipped with Bluetooth so that a lock can be opened and managed via the application functions. The users’ lock information in real time can be stored and managed in the database via a server that a server manager builds and manages. Even though users forget the password, our proposed lock system also guides them to find it easily, and provides the user’s manual. Using this system, users can do a variety of management functions such as adding, deleting, modifying, and purchasing the user’s own locks.
