Logic Gates Playground

This is a Processing 3 program that allows you to mess around with logic gates.

Loading the Example

I have made an example circuit that adds two four bit binary numbers. You can try it out by running the program then, pressing 'l' on your keyboard to load a save. The file is saved at Logic_Gates_Playground/data/4_bit_adder.json.

Making Your Own Circuits

You can make your own circuits using the Circuit class in Processing or visually using the UiState class. By default the program uses the UiState class.

To make gates visually, first run the program. You can create new gates with the following keys:

• 'a': AND
• 'A': NAND
• 'o': OR
• 'O': NOR
• 'x': XOR
• 'X': XNOR
• 'n': NOT

You create new connections by clicking and dragging from the output node of a gate to the input node of another gate.

You can pan and zoom around the circuit using the middle mouse button and the scroll wheel.
