Add the boolean operator NOT to indicate the inverse of a condition

  • Use the NOT operator ! to indicate an inverted condition (i.e. true becomes false, false becomes true).

NOTE: In the example above, the while loop continues while the brain's screen is NOT pressed. If/when the screen is pressed, the program exits the loop and carries out the subsequent commands for displaying text and moving forward. 

NOTE: It is easier to use boolean operators if the outcomes of conditions are considered. Logical truth tables like those below are used to track input conditions and output behaviors.

Code that can be copied and pasted:

#include "robot-config.h"  

int main() {
    //Loop to have the robot stay stationary until the screen is pressed.
    Brain.Screen.print("I'm moving forward for 3 seconds!");
