Ian Cole‘s excellent pinball machine project via raspberrypi.org:
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
Game event sounds
(Your average pinball machine in 1976 did not have HD graphics. Or any graphics at all. And it did not have 512MB of RAM.)

Make a robot friend with Adafruit’s
CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
