so does this mean that in the arduino world.. a LOW code for a button means that the button is pressed and a HIGH code means that the button is not pressed...!?
No, it just depends on if you want to add an external pull-down resistor between the pin and ground or not. Both ways work, one requires a resistor the other utilize a programmable internal pull-up resistor that is free.
If you have an example or tutorial sketch/schematic that having you wire the button between +5 vdc and an input pin, but showing no pull-down resistor wired between the input pin and ground, then you have a poor/incorret example/tutorial and that's a fact.
