I'm fairly new to arduino, but have done some parallax basic stamp hobby projects in the past.
One thing that I am having a bit of trouble wrapping my head around is how to properly define a numeric variable.
In the basic stamp world, because of limited program space, you had to be careful about how you defined the size of a variable to conserve resources.
So, I'm used to thinking about when I would want to use a bit, nibble, byte, or word.
But in arduino, all i see in most samples, and most posts, is the usage of int.
What am I missing here?
Is it not necessary to worry about when to define a variable as a bit, nibble, byte or word?
