Ok, lets say a penny slides down to the detector. It will not slide by because it is too big to pass because the detector is currently positioned at default which is to only pass a dime. The NXT now knows that the coin is not a dime because nothing passed the light sensor. The NXT program now increments? a variable which now becomes set to 1. The detector then rotates and the penny slides down past the light sensor and the NXT now knows the coin is a penny which is a variable value of 1.

The first coin sorter used a vertical rotating coin size detector. The size of the pieces that detected the type of coin would not retain the coin between each testing section. The coin would have to side back to hold? it while the next size detector piece rotated into place. Another reason I used this detector tilting mechanism for the first sorter was so the separator and it’s ramp could be lower.
