Help with motion activated servo please.

My bad, I've amended it.

But not reposted it.

When I say resting, I mean in the start position.

Servos don't have "start postion"s. They have whatever position they were in when they were powered off.

I would prefer that it just stay in it's normal default/idle state + position, and only move when motion is detected, then return to it's idle position.

When motion IS detected? Or, when motion BECOMES detected? Not the same thing at all.
