Here is an Arduino project that should prove attractive to Star Wars fans. We are talking about an Arduino powered, Xbox 360 controller controlled AT-AT Walker. The left and right triggers move the toy forward and backward while the right stick moves the head horizontally. Dave Stein, a software engineer, is behind this project.
The developer used an old AT-AT Walker, an Arduino Uno, an Adafruit Servo Shield, and a few other parts to start this project. You can find out more on his website.
