Abstract
This thesis presents the design and development of a dynamic display case controlled by stepper motors using an Arduino microcontroller. The primary objective
of this project is to enhance the viewing experience in physical museum exhibitions, particularly for three-dimensional items that are often displayed behind glass and cannot be touched by visitors. The dynamic display case allows for indirect interaction, enabling viewers to obtain a complete view of the exhibited items without physically handling them. The system utilizes NEMA 17HS4401 stepper motors, driven by A4988 stepper motor drivers, controlled by an Arduino Uno R4. Rotary encoders are employed to provide control over the rotation angles of the display case. The display case features three modes of operation: full 360-degree rotation, 90-degree incremental rotation, and manual control via rotary encoders. The components of the display case were designed using SOLIDWORKS and fabricated with 3D printing technology. The results demonstrated the system's ability to accurately control the rotation angles of the stepper motors, with minimal error rates. Additionally, power consumption tests highlighted the efficiency of the Arduino Uno compared to the Raspberry Pi 4. In
conclusion, this project successfully developed a dynamic display case that enhances the museum viewing experience by providing a complete, interactive view of untouchable items. Future recommendations include addressing the limitation of wire hindrance through the implementation of custom-made slip rings to facilitate unrestricted rotation.
