Arcade machines have evolved to support a variety of external peripherals, such as light guns and racing wheels, to enhance gameplay immersion. These peripherals connect through standardized interfaces like USB, serial ports, or custom connectors, depending on the machine's design. Light guns often use infrared sensors or screen scanning technology to detect hits, while racing wheels rely on force feedback mechanisms for realistic steering. Modern arcade systems may also include software calibration tools to ensure compatibility. By integrating these peripherals, arcade machines deliver a more interactive and engaging experience, appealing to both casual and hardcore gamers.
