See attached files:
when the simple software is launched it shows a screen identical to the one illustrated in "project.pdf" (but all boxes are initially red).
Each box toggles between red to green (and vise verse) only when a preassigned keyboard key is pressed
The assignment for the relevant key for each box is done in a separate data file that can be edited by the user before running the software (see Project [url removed, login to view] for reference).
The software will be used on a PC with windows xp or 7
