How much Arduino to replace most of that? [Old pinball machines are amazingly complex] It makes me appreciate how much Atmel packed into ATmega MCU's for such low prices. The things are so self-contained they have an internal clock source.

Part 3. I'm looking at state machines. [Tilting, taking turns, and winning free games: the many tricks inside old pinball machines]

Nothing can beat an electro-mechanical pinball machine. The feel and the sound, a MCU can never replicate that. Tom.... :smiley: :+1: :coffee: :australia:

Sound, vibration and lights can be activated (need the Part 3 Knockers!), the ball and table need 24V activation. Audio could include relay noises and piezos might drive a subtle vibration though logic and outputs are chip and transistor. This thread is more about how code could model physical mach…
