Why This Site Exists
Digital logic is usually taught with static diagrams and truth tables on paper. Those are precise, but they make it hard to develop a feel for how signals actually move through a circuit — why a carry ripples through an adder, or how two cross-coupled NOR gates can remember a bit. logicsimulation.com was built to close that gap: every concept on the site can be opened in an interactive simulator, changed, and tested immediately.
Who It Is For
- Students taking digital electronics, computer architecture or discrete mathematics who want to check their homework circuits and build intuition.
- Teachers who need a live, projector-friendly demo of gates, adders, multiplexers and flip-flops.
- Hobbyists who want to try a design before wiring it up on a breadboard with 74-series chips.
What You Will Find Here
- A drag-and-drop circuit simulator with all basic gates, flip-flops, multiplexers, adders, clocks and 7-segment displays.
- A 12-chapter tutorial, a library of 39 example circuits and 27 graded challenges inside the simulator.
- Reference guides on individual gates, boolean algebra, Karnaugh maps and common circuits such as the full adder.
How It Is Built
The simulator is written in JavaScript and runs completely in your browser. Circuits are evaluated on your own device, and saved circuits are downloaded as files to your computer rather than uploaded to a server. The site is developed and maintained independently.
The site is free to use and is supported by advertising. See the privacy policy for details on how ads and analytics work.
