Motor response speed to auditory and visual stimuli is considered one of the essential abilities contributing to optimal performance, especially in team sports that require quick interaction with a dynamic environment. Therefore, this research aims to design a modern, simple, and cost-effective electronic device to measure the motor response time to combined auditory and visual stimuli, and to develop a scientific test based on this device for accurate measurement. This contributes to supporting coaches and researchers in enhancing athletic performance. The research was conducted on players from the University of Anbar’s team sports, within the indoor hall of the College of Physical Education and Sports Sciences – University of Anbar, during the period from November 2, 2025, to January 4, 2026.
