Logic Circuit Lab: Logic Gates

Logic Circuit Lab is a pocket digital electronics lab. Drag gates onto a board, wire them up and watch signals flow in real time. Learn how computers think, from a single AND gate to adders, multiplexers, flip-flops and counters. Perfect for students of CSE, EEE, ECE and physics, teachers, hobbyists, and anyone curious about how digital logic works. LEARN STEP BY STEP - 20 interactive lessons with live circuits: binary, NOT, AND, OR, NAND, NOR, XOR, XNOR, Boolean laws, De Morgan, universal gates, adders, MUX, decoder, latches, D and JK flip-flops, counters and K-maps - Gate quick reference with symbols and truth tables SOLVE 40 PUZZLE CHALLENGES - 6 chapters: Basic Gates, Universal Gates, Real-World Logic, Arithmetic, Data Routing and Memory - Earn up to 3 stars by using the fewest parts - Hints when you get stuck BUILD ANYTHING IN THE SANDBOX - Switches, buttons, clock, constant HIGH/LOW - Gates: Buffer, NOT, AND, OR, NAND, NOR, XOR, XNOR with 2 or more inputs - Outputs: LED, buzzer, hex display, 7-segment display - Blocks: half adder, full adder, MUX 2:1 and 4:1, DEMUX, decoder, encoder, comparator - Memory: SR latch, D, JK and T flip-flops, 4-bit counter - Pinch to zoom, undo/redo, notes, colors, auto-save - Turn any circuit into your own reusable chip SMART TOOLS - Automatic truth table for any circuit - Simplified Boolean expression (sum of products) for each output - Expression to Circuit: type Boolean algebra, get a working circuit - K-Map Solver for 2 to 4 variables - Number Converter: binary, decimal, hex and octal EXPLORE 15 READY-MADE CIRCUITS Blinker, door alarm, half and full adder, binary to hex, counter, LED chaser, traffic light, latch, push toggle, majority vote, 4-input MUX, 2-bit adder, safe lock and parity checker.
