Disc movement

Hello Everyone,

I am trying to move the disc object by selecting the spinners on its edges with the mouse. Meaning if i touch the spinner i should be able to rotate it enough to see the green ball to your front.

I can do it with buttons but i am sure can be done the other method which i would like to do it which is by mouse selection. Can anyone help me with this.

Ex: so i should be able to press onto the spinner and then drag it up or down or in rotation basicaly forcing the disc to do as the spinner bids but rotation has to be in z direction.

Thank you
