Arcade game machines rely on various sensors to create an immersive and interactive gaming experience. The most common types include:

1. Joystick Sensors: These detect directional movements and are essential for classic arcade games like Pac-Man and Street Fighter.

2. Button Sensors: Found beneath arcade buttons, they register presses for actions such as jumping or shooting.

3. Motion Sensors: Used in modern arcade games to track player movements, enhancing games like dance or sports simulators.

4. Optical Sensors: Often used in light-gun games to detect where the player is aiming on the screen.

5. Touch Sensors: Common in interactive screens or touch-based games, providing a direct input method.

These sensors ensure precise and responsive gameplay, making arcade machines a favorite among gamers worldwide.
