This guide will describe the steps required to build Skull Ball, a DIY interactive game using a teensy microcontroller and a Sharp IR sensor to count ping-pong balls being thrown into a plastic cup mounted in a plastic skull.
I built this project in about 5-6 hours the week of my company Halloween party as a little interactive game for people to play. It isn’t terribly difficult to build and it could easily be rebranded for any major holiday or event. The concept is based on a cross between beer pong and Skee-Ball. The exact dimensions shown will most likely need to be modified to fit your specific need.
