Here is a link to my first Arduino project. It is a foam based Halloween skeleton I used as a basis for this prop. I built the 3 axis neck assembly and attached 4 futaba servos to the assembly. Yaw, pitch and roll are all servo driven as well as the jaw movment.
I had hoped to have the jaw servo positioned by sampling the output of the Ladyada waveshield DAC and using that sample to generate jaw movement synced to the wave playing. Ran out of time and knowledge before Halloween . The program is very simple I use 3 random number generators to generate the yaw, pitch and roll servo positions within the confines of the natural looking physical limits of skull travel.
I am also using 2 blue LED's drilled into the eyes (red plastic beads) and driven from all on 100% bright to off using PWM output in a timer loop.

Cool application of available hardware, and great project to reference people to who've got no idea where to start.

Thanks for sharing.
