Know when to use what resistor and then what value is not straight forward to me and trying to figure out a simple way to remember to know which to use.

Thanks -
The logic of true determines which to use, if true = 1 then use pulldown, as the pulldown makes it default to false. If true = 0 then use a pullup, pullup makes 1 default to false.
