 +// Use the Parola library to scroll text on the display
 +//
 +// Demonstrates the use of the scrolling function to display text received
 +// from the serial interface
 +//
 +// User can enter text on the serial monitor and this will display as a
 +// scrolling message on the display.
 +// Speed for the display is controlled by a pot on SPEED_IN analog in.
 +// Scrolling direction is controlled by a switch on DIRECTION_SET digital in.
 +// Invert ON/OFF is set by a switch on INVERT_SET digital in.
 +//
 +// UISwitch library can be found at https://github.com/MajicDesigns/MD_UISwitch
 +//
 +// NOTE: MD_MAX72xx library must be installed and configured for the LED
 +// matrix type being used. Refer documentation included in the MD_MAX72xx
