Logic Gates Visualisation

Explore digital logic fundamentals.

Logic gates are the basic building blocks of every digital circuit — from a calculator to a CPU. Each lab here lets you flip inputs on and off and watch the output respond immediately, alongside a full truth table so you can see every possible input combination at a glance. Work through AND, OR, and NOT first to build intuition for the fundamentals, then move on to the derived gates — NAND, NOR, XOR, and XNOR — to see how more complex logic is built from simpler pieces.
