Build your own animatronic hand using cardboard, straws, some cord, and rubber bands. Pull the cords to actuator fingers -- or even better, let some servo motors do it for you!

CRICKIT is the perfect platform for building your animatronics projects -- it can take commands from your Circuit Playground Express and then power your servos. You can even add lights and sound later if you like.
