Make your own animatronic eyeball that can look around -- left/right and up/down -- to add to your costumes and props, or simply as a (slightly unnerving) decoration!

With a pair of servo motors and a Crickit board paired with Circuit Playground Express, you can control the animatronic gaze with pre-programmed movements, random glances, or even interactive control.
