Build it from logic gates

Short, hands-on guides to building the core building blocks of digital logic from gates, each with a live circuit you can toggle right on the page and open in the lab.

Every part below is realized and verified by the same simulator that powers the digiwleea lab, so the embedded circuit is the exact one the walkthrough describes. Pick one to start:

• Build a half adder →
• Build a full adder →
• Build a 2:1 multiplexer →
• Build a SR latch →
• Build a D flip-flop →
