// Playfield: This is the main code for driving the functionality of an interactive pinball playfield.
// The playfield intends to update scoring based on the ideas of baseball at each base (single, double, triple) and 
// outfield (homerun). The functionality updates pins HIGH/LOW to launch the ball back after the photoresistor 
// inside each hole detects the ball.
