The Simulation Window allows for data to be simulated for the six analog inputs for the Uno or 16 analog inputs for the Mega. The window may be resized to be smaller, and the scrollbars and text boxes will automatically resize to suit.

The ShiftIn and PulseIn allow the return values for these functions to be set.

The Analog Value may be changed by moving the respective scrollbar, or entering a new value in the white Edit box.

Input and Output data is displayed in five ports. Each port has its own line for input data and a box for output data. Each Port can be expanded or contracted to suit the display and resized.  

The ports are assigned in the order they are setup.
