Traffic-light controller Karnaugh map

This Karnaugh map lays out a traffic-light controller output in Gray-code order, where adjacent cells differ by one variable. The ones form two four-cell regions, giving a clear visual basis for simplification. The heatmap representation makes the minterms legible at card size, but the group boundaries and final Boolean expression should be confirmed from the stated function. Use variable names that match the associated truth table so an engineer can trace each cell back to the controller inputs. Before sharing it, compare the chart with the source table and make the scope explicit. A clear date range, population and unit help another reader interpret the pattern correctly and decide whether follow-up analysis is needed.

FAQ

Frequently asked questions

What does this heatmap show?01

A heatmap uses colour to show the size of a value at the intersection of two categories. It helps readers spot concentrations, gaps and repeated patterns quickly.

How should I read this heatmap?02

Choose a colour scale whose minimum and maximum match the data, and include cell labels when precise values matter to the decision.

Can I adapt this heatmap example?03

Yes. Replace the title, labels and values with your own data, then check that the prompt still describes every important element in the chart.
