NOTE: The code above `(sizeof(Rings)/sizeof(Rings[0])` is a way of having the compiler calculate the count of elements in the Rings array without us hardcoding anything. Often this is exposed as `_countof()` in many code based but it was not included in the Arduino headers for some reason.

### Making the object usable for different collections of rings
The above code hard codes the array of values. We can make this a configuration argument to the constructor of our mapping class and thus reuse the code for different projects.
