For a class assignment, Matt Robb along with teammates Kara and Andrew needed to make a project using an Arduino and various other components. What they came up with was a carnival-style game that uses a stepper motor to rotate three targets containing IR sensors out of a nicely-painted cardboard box.
An Arduino Uno provides control for the game. When hit with a signal from an IR remote, an LED on the target goes out, a buzzer beeps, and it momentarily stops spinning.
It looks like it was a lot of fun to build and play, so be sure to check it out in the video seen here!
