Chris over at The New Hobbyist has recreated the four singing Grim Grinning Ghosts of Disney’s Haunted Mansion attraction on his porch and has provided detailed instructions on how to make them using styrofoam heads, an Arduino UNO board and various parts.
So once you’ve got your hardware and software all playing nice the only thing left to do it arrange the heads in a trick-or-treater friendly area and wait to BLOW KIDS MINDS. The neighborhood kids seemed to really get a kick out of the display (some coming back with friends to show them). It was a lot of fun and taught me a thing or two about the Arduino.
