Every logic gate takes binary inputs and produces a binary output. Flip the switches below and watch the signal travel through each gate — then test yourself in the practice section.
Choose a gate, toggle its inputs, and watch the output and truth table respond live.
The six standard gates, their symbols, and both ways of writing them: logic notation and Boolean algebra.
You're given a gate and its input values. Work out the output before you click.
