This leprechaun stays hidden until the motion detecting sensor notes an object in front of the dollhouse. The Arduino then calls the stepper motor to cause the articulating arm to push the leprechaun out the front door. Four servos then make the leprechaun dance the Swallowtail Jig. It’s a nice St. Patrick’s Day greeting to all who come to our home!
