Next, you will be taking a closer look at the conditional, if (rotationState == 1).Within the parenthesis is the
expression whose condition must be met in order to do what is inside the curly brackets. Of note is the double equal
sign; this is the equivalency operator, and it checks to see if the variable rotationState currently holds the value of 1.
If so, inside the curly brackets, it updates the value of rotationState to 0, so now rotationState = 0 (the single
equal sign being the assignment operator). Otherwise, you get else if (rotationState == 0), the rotationState is
currently 0, so set it to 1, rotationState = 1. After the state has been identified and updated, you will have it printed
out to the console, as in print("State = " + rotationState).
