Hello! I'd like to have 3 dials and based on the position of each when a button is pushed a different image will show. My question is how to map the image to the correct combination of dial positions. Something like, if a = 2, b = 3, c = 4, then image = apple; if a = 3, b = 2, c = 6, then image is orange....and so on for 20 or so combinations/images. Your help is greatly appreciated!
