Lesson 1Electronic control and payout logic: hopper drivers, fuses, coin counters and PCB rolesExplains how slot circuits direct and watch hopper payouts. Covers driver paths, fuses, switches, coin tallies, and board reasoning, including start lines, payout beats, fault spotting, and link to main game processor.
