Truth Table: Build a circuit and toggle switches to test
Circuit Designer ×
Select a component from the palette, then click grid cells to place.
Components: Switch (input), AND/OR/NOT gates, LED (output), Wire (path).
Connections flow orthogonally through wires. Gates read from left/below, output to right/above. Place AND/OR with 2 inputs below, output above. NOT is vertical: input below, output above.
Evaluate generates the truth table by testing all switch combinations. Complete challenges by matching expected truth tables with minimal components!
