I was building a little ripple carry adder in the popular sandbox game Minecraft when I suddenly got the idea for this program.\n\n## Use cases\nThis program can be used to understand how logic gates work, visualize complex structures or just play around with different gates.\n\n## Controls\n- Hold left click to drag nodes / draw connections\n- Right click to remove a node\n- Hold middle click to move the whole screen\n\n## Available gates\n- AND, OR, XOR, NOT (Inverter)\n- Splitter (Takes a signal and outputs the same signal twice)\n- BCD to 7-segment display gate\n\nThe following are not really gates, but I don't know where else I could list them:\n- Input (Can be altered by the user; Double click to toggle the state)\n- BCD Input (Converts a decimal into a binary-coded decimal)\n- Output\n- 7-Segment display output\n\n## Known bugs\n- StackOverflowError when creating infinite recursion ([#1](https://github.com/RealCerus/logic-builder/issues/1))\n\n## Todo\n- Finish javadoc comments ([#2](https://github.com/RealCerus/logic-builder/issues/2))\n- Add Json exporter and importer ([#3](https://github.com/RealCerus/logic-builder/issues/3))\n- Add a tool to create custom gates from Json exports ([#4](https://github.com/RealCerus/logic-builder/issues/4))\n- Maybe add more gates?\n\n## Gallery\n\u003cdetails\u003e\n\u003csummary\u003eClick to expand\u003c/summary\u003e\n\n\u003cimg src=\"https://nobody-will.make-america-great-aga.in/nQvECTDNdeNnKlKR\" alt=\"Picture 1\"\u003e\u003cbr\u003e\n\n\u003cimg src=\"https://nobody-will.make-america-great-aga.in/PbkkPDavKIyMyUyR\" alt=\"Picture 2\"\u003e\u003cbr\u003e\n\n\u003cimg src=\"https://nobody-will.make-america-great-aga.in/oHKOUfAIduqUzmZN\" alt=\"Picture 3\"\u003e\u003cbr\u003e\n\n\u003cimg src=\"https://cerus-dev.de/img/logic-builder-7-segment.gif\" alt=\"Picture 4\"\u003e\n\u003c/details\u003e\n\n## License\n[MIT](LICENSE)\n\n## Contributors ✨\n\nThanks goes to these wonderful people ([emoji key](https://allcontributors.org/docs/en/emoji-key)):\n\n\u003c!-- ALL-CONTRIBUTORS-LIST:START - Do not remove or modify this section --\u003e\n\u003c!-- prettier-ignore-start --\u003e\n\u003c!-- markdownlint-disable --\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n    \u003ctd align=\"center\"\u003e\u003ca href=\"https://cerus-dev.de\"\u003e\u003cimg src=\"https://avatars3.githubusercontent.com/u/46848982?v=4\" width=\"100px;\" alt=\"\"/\u003e\u003cbr /\u003e\u003csub\u003e\u003cb\u003eMaximilian\u003c/b\u003e\u003c/sub\u003e\u003c/a\u003e\u003cbr /\u003e\u003ca href=\"https://github.com/RealCerus/logic-builder/issues?q=author%3ARealCerus\" title=\"Bug reports\"\u003e🐛\u003c/a\u003e \u003ca href=\"https://github.com/RealCerus/logic-builder/commits?author=RealCerus\" title=\"Code\"\u003e💻\u003c/a\u003e \u003ca href=\"https://github.com/RealCerus/logic-builder/commits?author=RealCerus\" title=\"Documentation\"\u003e📖\u003c/a\u003e \u003ca href=\"#ideas-RealCerus\" title=\"Ideas, Planning, \u0026 Feedback\"\u003e🤔\u003c/a\u003e\u003c/td\u003e\n    \u003ctd align=\"center\"\u003e\u003ca href=\"https://bitbucket.org/Paul2708/\"\u003e\u003cimg src=\"https://avatars2.githubusercontent.com/u/12039677?v=4\" width=\"100px;\" alt=\"\"/\u003e\u003cbr /\u003e\u003csub\u003e\u003cb\u003ePaul\u003c/b\u003e\u003c/sub\u003e\u003c/a\u003e\u003cbr /\u003e\u003ca href=\"https://github.com/RealCerus/logic-builder/commits?author=Paul2708\" title=\"Code\"\u003e💻\u003c/a\u003e\u003c/td\u003e\n  \u003c/tr\u003e\n\u003c/table\u003e\n\n\u003c!-- markdownlint-enable --\u003e\n\u003c!-- prettier-ignore-end --\u003e\n\u003c!-- ALL-CONTRIBUTORS-LIST:END --\u003e\n\nThis project follows the [all-contributors](https://github.com/all-contributors/all-contributors) specification.
