Electronics: Binary multipliers simulation (LogicGates7).

Description: Electronics related application, showing how logic gates can be used to design binary multipliers. The program is a simple interactive simulation of a 2x2bit-, a 4x3bit- and a 4x4-bit-multiplier, where the user can choose the circuit's input by opening/closing a switch, letting the current flow and observe the output as LEDs going on or off. To action the switches, just click on them. LEDs with solid color indicate high voltage, LEDs with a pattern color, low voltage.

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". Using digits sub-scripts. Boolean operations (classic Pascal).
