Logic Circuit Builder
Build digital logic circuits in your browser with our interactive Logic Circuit Builder. Whether you're learning computer science, preparing for exams, or just curious how computers think, this tool lets you experiment with the fundamental building blocks of digital electronics.
Logic gates are the foundation of all digital systems. An AND gate outputs 1 only when both inputs are 1. An OR gate outputs 1 when at least one input is 1. A NOT gate inverts its single input. XOR (exclusive OR) outputs 1 when inputs differ. NAND and NOR are the negated versions of AND and OR. By combining these gates, you can build adders, multiplexers, and eventually entire processors.
Our simulator features real-time signal propagation: toggle an input switch and watch the signal flow through your wires instantly. Wires turn green when carrying a 1 (high) and gray when carrying 0 (low). Output LEDs light up to show your circuit's result. Start in Sandbox mode to explore freely, then tackle our five challenge puzzles - including building a half adder and matching truth tables - to test your skills.
No installation required. Everything runs in your browser. Use the gate palette to add components, drag wires between connection points, and solve challenges. Perfect for students, hobbyists, and anyone interested in how logic circuits work.
