So I have been looking around for someone who has Motion Plus working with Arduino 1.0, but I came up empty handed. So I took two existing sketches, one with just the motion plus, and another with MotionPlus + Nunchuck, and I updated them to work with Arduino 1.0!
Here is the simple one.
And here is the more complex (MotionPlus + Nunchuck).
I hope everyone finds this useful, at some point I will be adding a MotionPlus to one of my projects 🙂
