If you’ve been looking for inspiration or ideas for your next Halloween decoration, then consider this fun project idea. I’ve been looking for ways to make a simple and inexpensive project that highlights our Limited-Availability Parallax Animation Kit (#). Turns out that Halloween naturally provides a great setting for this type of application. So, I made a trip to the dollar store and purchased an inexpensive felt prop with movable joints. Standard servos provide a perfect means to add some movement to the prop and adding a speaker allows it to play a song (or whatever spooky sound you have in mind).
For this project each servo moves one limb and I decided to provide movement to each limb (arms and legs) so I needed 4 standard servos. The Animation Kit comes with 2 standard servos, and the code I used can easily be modified to work with just two servos for the arms or possibly the head and one arm. Ok let's have some fun!
