Booleans work the same as in most languages. If you want to test for a
certain condition or set of conditions, then break it down into things that
can be answered as true or false.
You can use equalities, such as:
if (sky == blue) printf ("you're on earth") ;
if (sky != blue) printf ("you're not on earth") ;
you can use realtionship tests such as:
if ( franks_age <= bobs_age ) <some code here>;
if ( franks_age >= bobs_age ) <some code here>;
you can also force conditions, such as
while (0==0) <some code here>;
Some things that I usually use booleans for are testing if an analog sensor
is above or below a certain level, a switch is depressed, or a loop has
executed the desired number of times.
Hope that helps.
