Description: Electronics related application, studying logic gates (resp. logic operators from a mathematics point of view). The program is a simple interactive simulation of logic gates circuits, where the user may choose the gate's input by opening/closing a switch letting the current flow and observe the gate's output as a LED going on or off. To action the switches, just click on them; a green LED going on indicates that the corresponding gate input is high. The red LED at the output side of the gate goes on or off as indicated by the logic operator's truth table.

Change log:
Version 1.0 (March 2018): Original program.
Version 1.1 (August 2021):
    - Adapting position and width of input wires to gate image (proper display).
    - Some minor code modifications.

Free Pascal features: Interactively changing color and position of shapes. Filling string grids.
