Stop staring at static textbook diagrams. Learn Electronics Simulator lets you toggle inputs, watch outputs change in real time, and actually understand how digital circuits work — from basic AND gates to 16-bit shift registers.

━━━ WHAT'S INSIDE ━━━

75+ fully interactive circuit simulations organized into a structured learning path:

LOGIC GATES (20 simulations)

AND, OR, NOT gates with 2 to 5 inputs. NAND and NOR universal gates (with propagation delay modeling). XOR and XNOR exclusive gates. Every gate shows live truth tables — the row matching your current inputs highlights automatically.

ARITHMETIC CIRCUITS (11 simulations)

Half Adder, Full Adder (standard and NAND-based), Parallel Binary Adder, Serial Binary Adder, Half Subtractor, Full Subtractor, Parallel & Serial Binary Subtractor, and a 4-bit Parallel Multiplier. Each shows binary-to-decimal conversion in real time.

COMBINATIONAL CIRCUITS (7 simulations)

4-to-1 Multiplexer, 1-to-4 Demultiplexer, 2-to-4 and 3-to-8 Decoders, Decimal-to-Binary and Octal-to-Binary Encoders, BCD-to-7-Segment Decoder.

FLIP-FLOPS (16 simulations)

NOR and NAND SR Latches, Clocked SR, D Flip-Flop (5 variants including Preset & Clear), J-K Flip-Flop, Edge-Triggered J-K, J-K Master-Slave (with Preset & Clear), T Flip-Flop. Waveform display shows clock and output signals over time.

COUNTERS (12 simulations)

Asynchronous and Synchronous Up/Down Counters, Mod-3, Mod-5, Mod-6, Mod-10 Counters, Ring Counter (8-bit), Johnson Counter (8-bit). Watch binary count change with each clock pulse.

SHIFT REGISTERS (7 simulations)

SISO (16-bit), SIPO (16-bit and 4-bit), PISO, PIPO, Bidirectional Shift Register, Universal Shift Register. See bits physically move through the flip-flop chain.

PROJECTS (4 hands-on demos)

Counting with 7-Segment Display, Spinning LED Effect (Ring + Johnson Counter), Color Changing Christmas Light, 32-output Scrolling LED Display.
