Electronics: SR and D-type latches simulation (LogicGates5).


Description: Electronics related application, showing how logic gates can be used to design common electronic circuits. The program is a simple interactive simulation of a variety of RS and D-type latches, using NAND or NOR gates, with or without being gated (controlled by an Enable signal). The user chooses the circuit's input by opening/closing a switch, letting the current flow and observe the output as LEDs going on or off. Explanation of the latches' functionality and truth tables included.

Free Pascal features: Combining images and shapes to create layouts. Interactively changing brush style and position of shapes. Using transparent images as "click-on areas". Boolean operations (classic Pascal).
