Creep out guests with an Arduino-controlled teddy bear
Arduino Team — November 14th, 2018
Halloween has become something of a hacker holiday, giving creative people the world over a chance to show off their spooky animatronic inventions outside without neighborhood scrutiny. This year, Instructables user “gocivici” created a display inspired by the doll in a rocking chair featured in the movie Annabelle, but decided to use an Arduino-infused teddy bear instead.
The setup is simple but effective, using an Arduino Nano and solenoid to rock the chair. The bear’s head rotates using another Arduino board—an Uno this time—along with a second solenoid and 3D-printed assembly stuffed inside. Control is accomplished via a small wireless remote, though a motion sensor could also be employed.
