Our final design project was a Mini-Golf (Putt-putt) game complete with a 9-hole course and scoring system. 

We decided to do a Mini-Golf game because we both enjoy golfing, and this was the best way we thought we could bring this interest into a Microcontroller project.  We wanted the game to emulate, as closely as possible, a real Mini-Golf atmosphere with obstacles and variously shaped holes.  Another goal in our design was to keep the system small and mobile so the fun of Putt-putt could be taken anywhere anytime so long as there is a 9V battery handy and a TV with RCA inputs.  Additionally, having the system completely portable would allow us to show the project off to our friends and families
