Need to create a spinwheel like a Jackpot wheel, such that when a user clicks on START button, it should spin and a Needle to point on wheel, while the results should be pre-saved by us.
I think you need to program the deceleration. how fast is the wheel the moment it decelerates. where will it be on the current deceleration rate and how much is it off from the desired result? with the adjusted deceleration rate it should then halt where you want it to.
