A miniature theme park programmed and ran by 1 Arduino MCU + 1 RPi. There are 3 segments to the park - the pokeball shooting game, the Ferris wheel, and a thrilling carousel ride. 

In the pokeball shooting game, the pikachu target is programmed to constantly bounce between 2 limit switches, while the player then uses the controls to aim and fire the pokeball shooter (which is powered by a stepper motor and a DC motor).

For the ferris wheel, a stepper motor is used to control the precise rotation of the ride. Light gates are at embedded at the bottom of the ferris wheel to detect when a carriage passes. This allowed the Ferris wheel to stop at each carriage to load passengers, and after all 8 carriages are loaded, the ferris wheel will run continuously for a minute. 

For the thrilling carousel ride, I made a linear actuator using sets of worm gears and a drive train, which allowed a dc motor's rotations to translate into linear motions. This gave the ride the ability to move vertically up and down. At the top of the linear actuator resides another Dc motor, which allowed the carousel to spin at varying speeds.
