Abstract: This paper presents a sensor-based gaming system that enhances interactivity by leveraging the ESP32 microcontroller and ultrasonic sensors to enable real-time motion-based control.

The system uses ultrasonic sensors and a servo to aid in obstacle detection and an ESP32-CAM to help recognize the object in front of the user. The servo is used in a sweeping motion to achieve a ...
