🔮 Logic Gates
Digital circuits are built from a handful of logic gates. Pick a gate, toggle the inputs A and B, and watch the output and the full truth table update live. This is the hands-on companion to the Digital Concepts reference — it trains the Associate CET competencies 13.1 (identify gates) and 13.2 (construct truth tables).Understanding Logic GatesA clear walkthrough of how each gate works and how to read its truth table.external video · opens in a new tab

Choose a gate below, then flip the inputs. The schematic redraws, the OUTPUT lights up, and the matching row in the truth table highlights so you can connect the symbol to its behavior.
