The name of our final year project is Barcode Search System. We usually come across areas where a user needs to find and identify the books that they need. Here we propose a system that allow user to find the books that they want in the library. We propose to use Barcode Search System through computer in the library. Our system allows user to find the books that the user need. The system will receive the code of the books. The system also alerts the user if the books is available of times. The circuit consists of a computer that connect to the Barcode Search System to find the books that user need. The barcode books will be list into the Microsoft word that have been register in the system and sends it to microcontroller. The microcontroller reads the input and identify the code that have been set.
