ABSTRACT
Automated systems save the time and effort of individuals. It makes everyone’s lives more convenient and easier. This study aims to develop a computer-controlled book return system using a circuit, machines, barcode and a program made through Visual Basic software. The objectives include (1) creating machines that receives input from the computer to be delivered to the machines (3) and, to develop a Visual Basic program that control the hardware.
A system composed of a circuit and machine was constructed to enable communication between the computer and the hardware. The motors control the movement of the machines; the power supply proves power to the motor and the decoder decodes the binary coded inputs. A Visual Basic program was made to provide an interface for the user to control the machine with a display of the database.
Recommendations of the study include (1) adding more functions or machines in it (2) to accommodate a wider range of books in terms of size and length.
