Effect for Halloween, need help

[f150trk21]

Hey guys

Need some help figuring out how to do this. What I want to do is have a projector project a video on a fog wall and audio triggered by an event, say from a motion detector or those walk on mats. The video clip will just be a few seconds long of a monster face and audio of screaming. Any ideas on how to play the video and audio clip say from a PC everytime a victim triggers it?


thanks
Jason

I would get a throwaway mouse and hook your activation trigger to the mouse button switch.

Thanks for the idea. I just found out an arduino Teensy can act as a keyboard and that'll work great.

That works and knock-off arduinos are about as cheap as they come too. Post pics when you get this going
