I just got around to compiling my Halloween project for my blog and I thought I'd share my project here as well.
I put together a small scale recreation of the Disneyworld/land Haunted Mansion singing busts from the ride. I think it turned out pretty cool.
I have an Arduino UNO hooked into a photocell switch used to activate the playback of the video file.
The audio ended up being a little out of sync after running through iMovie and YouTube, not quite sure why. The code and programs I used are all listed on my blog post.http://www.thenewhobbyist.com/2010/12/arduino-powered-haunted-mansion-halloween/
