-//What's needed is a global variable with its own name, for example:
-//int x;
-
-//Now, you set x to 1 inside the flip() function. In main(), inside the infinite loop starting with while (1) { , you check whether x ==1 and if it is, you print to the LCD and set x to 0.
-
-//(Be very careful about this. x=1 sets x to 1. x==1 compares x to 1.)
