When a button is pressed on a joystick, it is not remembered. If the motor was to be driven for some time and the user did not want to hold the button until the desired point, a flag would have to be used.

The flag would be set to one when the button is pressed which would enable code controlling relay ouputs or pwms. Once a desired outcome happens, the flag would have to be reset. The outcome could be a pot position being reached, an encoder count value, a set amount of time from either Kevin's clock or a clock variable incremented every program cycle, or even the ORIGINAL BUTTON pressed on the joystick.
