Free Logic Gate Simulator

Logic Gate Simulator test binary inputs, truth tables, and simple circuits online

Logic Gate Simulator helps students, teachers, and electronics beginners choose AND, OR, NOT, NAND, NOR, or XOR gates, switch 0/1 inputs, see the output instantly, and build a small multi-gate circuit with live explanations.

Built for quick Logic Gate Simulator practice before digital logic homework, electronics class, or a hardware lab.

Logic Gate Simulator interactive logic tool

Start Logic Gate Simulator here: choose a gate, toggle A and B between 0 and 1, inspect the highlighted truth table row, then drag gates into a simple circuit chain.

Logic Gate Simulator mode

Use one gate for a clean truth table, or switch to the circuit builder for chained gates.

Binary inputs

Click each input to switch between 0 and 1. NOT uses input A only.

Logic gates

Click a gate for the current mode, or drag it onto the circuit builder.

Logic explanation

Logic Gate Simulator is an educational Boolean logic model. It explains ideal logic gates and truth tables, not voltage timing, propagation delay, or physical chip behavior.

Logic Gate Simulator single-gate and circuit workflow

Logic Gate Simulator starts with clear single-gate results, then moves into a simple drag-and-drop circuit so the same 0/1 logic stays visible.

Logic Gate Simulator truth table focus

Choose AND, OR, NOT, NAND, NOR, or XOR and Logic Gate Simulator highlights exactly which truth table row explains the current output.

Logic Gate Simulator quick guide

Use this Logic Gate Simulator guide to connect a gate symbol, binary inputs, truth table rows, and the final output explanation.

01

Choose a Logic Gate Simulator gate

Start with AND, OR, or NOT, then compare NAND, NOR, and XOR. Keep the selected gate visible while you change the inputs.

  • Use 0 and 1 as LOW and HIGH
  • Start with one gate before chaining
Open simulator
02

Read the Logic Gate Simulator truth table

Toggle A and B and watch the highlighted row move. The highlighted row is the reason the output becomes 0 or 1.

  • Compare XOR and OR
  • Notice that NOT ignores B
See features
03

Build a Logic Gate Simulator circuit

Switch to circuit mode, drag several gates into the canvas, choose each second input, and read the step-by-step explanation.

For homework practice, predict the final output first, then use the circuit truth table to check your reasoning.

Logic Gate Simulator FAQ

Fast answers about Logic Gate Simulator gates, truth tables, circuit building, sharing, and learning scope.

Is Logic Gate Simulator free?

Yes. Logic Gate Simulator runs in the browser and can be used without an account or installation.

Which gates does Logic Gate Simulator support?

Logic Gate Simulator supports AND, OR, NOT, NAND, NOR, and XOR gates with binary 0/1 inputs.

Does Logic Gate Simulator show truth tables?

Yes. Single-gate mode highlights the active truth table row, and circuit mode recalculates a final truth table for all A/B input pairs.

Can Logic Gate Simulator build circuits?

Yes. The circuit builder lets you drag multiple gates into a simple chain and choose the second input for two-input gates.

Is Logic Gate Simulator an electronics timing simulator?

No. Logic Gate Simulator teaches ideal Boolean behavior. It does not simulate voltage levels, propagation delay, fan-out, or physical chip limits.

Start Logic Gate Simulator now

Open Logic Gate Simulator, choose a gate, switch A and B between 0 and 1, and see the output, explanation, and truth table immediately.

Then switch to Logic Gate Simulator circuit mode to drag multiple gates and test a simple digital logic chain.
