The Fireball Pinball machine is a 1976 game, which Ian bought in a very unloved state for a couple of hundred dollars. Using a Pi, he’s dragged it into the 21st century. Ian says:
The basic system design has the Pi as an i2c master with the following functions:
- reading switches from the lamp / switch Arduino when that slave pulls an interrupt pin hi (read by Pi GPIO after a level shifter)
- sending commands to the lamp / switch Arduino to turn on / off specific lights
- sending commands to the solenoid driver to fire specific solenoids
- Gameplay tracking – players, balls, scores, bonus
- Background music
- Game event sounds
- HD GRAPHICS!
(Your average pinball machine in 1976 did not have HD graphics. Or any graphics at all. And it did not have 512MB of RAM.)
