As you can see in the attached picture, this is my owl robot. It turns left to right 180 degrees... I want the piezoelectric ultrasound to control the servo thus starting it only when the ultrasound sense motion! (Someone walking by etc). Optimal would be if it could follow my movements right to left etc., like a turning head!
Also adding a sound like "hoot hoot" would be great (triggered by the ultrasound) with some led lights flashing up in its body and/or the ground.
Would all this be possible and where can I find code to knit it all together?
