Now i was able to make a small part of the wheel white so the photosensor has something to recognize. My question is how big should the mark actually be on the wheel for the photosensor to recognize it in a well fashioned time?

Please post a picture of the wheel showing the white mark. The shape and sharpness of the mark is important.
