Lesson 1Electronic control and payout logic: hopper drivers, fuses, coin counters and PCB rolesExplains how slot electronics direct and watch hopper deliveries. Covers driver paths, fuses, switches, coin tallies, and panel reasoning, including activation lines, delivery signals, error spotting, and link to main game processor.
