Karnaugh Map Solver

Intro

This project is a free online Karnaugh Map (K-Map) simplification tool. According to available site snippets, it accepts several input types (Truth Table, Boolean Expression, Minterm, Maxterm) and presents an interactive K-map interface. The interface shows a "Number of Variables" field and basic controls such as Clear All and Fill All. Cells can be clicked to toggle values in the sequence 0 → 1 → X → 0, where X represents a "don't care" condition. The solver produces SOP (Sum of Products) and POS (Product of Sums) results and provides step-by-step solutions for those outputs.

Key Features

• Multiple input methods: define the K-map from a truth table, Boolean expression, minterms, or maxterms (as listed in site snippets).
• Interactive grid: click cells to cycle values 0→1→X→0 and use controls like Clear All and Fill All.
• Variable control: a selectable "Number of Variables" field is exposed in the interface (snippets do not specify a maximum supported value).
• Solution output: generates SOP and POS forms with step-by-step explanation for the generated results.
• Learning resources: the site includes beginner-friendly blog articles and tutorials about Karnaugh Maps and digital logic.

Who this is for

• Students and learners seeking practical, beginner-oriented explanations and examples for K-map and Boolean simplification.
• Engineers or hobbyists who need a quick, interactive tool to simplify Boolean expressions using Karnaugh Maps.
• Users who want step-by-step SOP/POS derivations rather than just a final expression.

Note: the solver is described as free in available snippets. The site snippets do not show a privacy policy, detailed pricing information, explicit export/import options, or a stated maximum number of variables, so those details are not confirmed here.
