Electronics: XOR gates simulation (LogicGates2).
Description: Electronics related application, showing how Boolean algebra can be used to design XOR gates by
making logical circuits constituted of a combination of NOT, AND, NAND and/or OR gates. The program is a simple interactive simulation
of two such XOR implementations, where the user can 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 yellow LED indicate the output states of the intermediate gates, which are used as input for the
final gate. The red LED at the output side of the final gate goes on or off as previewed by the XOR logic.
