Someone had seen Peter Penguin or my Instructables on Animatronic Penguin Torso or Animatronic Eyes, and was working on a sculpture. He wanted to animate the sculpture when someone walked into the room and asked if I could do it. I thought about it for a while. There were several differences from my penguin, (no laptop controlling the action, could use an SSC-32 as I had before, but may be overkill, and I had never used a PIR Motion Detector before.) But after researching Arduinos and the motion detector from Roboshop ( http://www.robotshop.com/en/parallax-pir-motion-sensor.html ), decided to have a go.
SO this is Mark II of my Animatronic Eyes. The eyes do not rotate, but that wasn't requested. It would not be too difficult to add that feature back in, now that I have this model functional.
