LogicalArt is a digital logic simulator where you build a computer from nothing but logic gates. Wire NOT, AND, OR and XOR gates, switch on the power, and watch every signal travel through your circuit. No breadboards, no soldering, no tangled jumper wires. Just the ideas behind how a CPU really works, made visible on your iPhone, iPad and Mac. LEARN BY BUILDING: GUIDED CHALLENGES Work up a ladder of hands-on puzzles: Half Adder, Full Adder, Multiplexer, Decoder and a 1-Bit ALU. Label your inputs and outputs, tap Verify, and LogicalArt plays the whole truth table on your live circuit, row by row, so you see exactly where it works and where it doesn't. FROM GATES TO A CPU • Four basic gates: NOT, AND, OR, XOR. Everything else is built from them. • Package any circuit into a reusable chip, then build bigger designs out of your own chips. • Create EEPROM chips straight from a truth table. • Build latches, flip-flops, registers, counters, adders and an ALU, step by step toward your own 8-bit computer. SEE WHAT YOUR CIRCUIT IS DOING • Deterministic simulation with real gate delay, so clocks, latches and feedback loops behave the way they should. • Clock inputs, number displays and a live view of every wire's state. • Waveform view to follow signals over time. MADE FOR TOUCH, TRACKPAD AND MOUSE • Drag to place gates and draw wires; pinch, scroll and zoom around large boards. • Undo, labels and a clean layout that stays readable as your designs grow. • Native on iPhone, iPad and Mac. SHARE AND DISCOVER Browse boards from other builders and share your own. WHO IT'S FOR Computer science and electrical engineering students, teachers explaining digital logic, programmers curious about what happens below assembly and Verilog, and anyone who has ever wondered how a computer actually works. FULL ACCESS Start for free. A one-time Full Access purchase unlocks every feature: unlimited boards, chip packaging, EEPROM chips and sharing. No subscription required. Enjoying LogicalArt?
