hey there,

im trying to get my stepper to move back and forwards in half rotations with the speed of a sine wave...(slower at the ends, faster in the middle)....can anybody help me with a nifty bit of awesome code and i will be forever grateful.

thanks.

Check out the AccelStepper library, it will do what you want. Tweak the acceleration value until you get the effect you want.

Good luck!
