The sample code worked. It had a hard time "learning" to accept smaller coins but American quarters worked fine. The documentation and code from +Adafruit Industries
' site was very useful as the unit had no instructions and the box was in labelled in Chinese.
I also am going to use their Boarduino as it is cheap and small but also has a decent voltage regulator that should handle the servo. The coin op unit takes 12V so that will be what the regulator has to deal with.
