A little bit bent...
I'm going to try to build a talking Mr. Thrifty this year. I plan to have it clothed in a half-rotted little girls dress, and loop a soundtrack that repeats something like "Will you come play with me?" in a sweet little girls voice while it sits near the edge of the graveyard. I'm going to try to use a second input to the servo board that is a loud scream. This second input would be triggered by a PIR that is very directional and only triggers when the TOT is really close to the "little girl". The scream would be louder than the voice track and so would wash out the spoken words and drive the servo to max position. I'm also thinking of having LED eyes light up for the duration of the scream. So, has anyone tried using dual inputs to a servo board, and what results did you get? All advice is appreciated!
