Notice, we've added the ++ operator. Simply, the statement "buttonPresses++" increments (adds 1 to) the buttonPresses variable. This is a shortcut for "buttonPresses = buttonPresses + 1". We first saw this in the For Lesson from Chapter 5. In this sketch there is no new code to explain. you should recognize several things from previous lessons that ave been put together in new ways. Now it's time for you to extend on some previous ideas. Time to Play
