Logic Wiki — Every Logic Gate Explained

The free companion curriculum for the Logic Gates boards. Every gate explained with symbols, truth tables, and real-world analogies: BUFFER, NOT (inverter), AND, OR, XOR (the hallway light), NAND (the safety alarm), NOR, and XNOR — plus sequential logic topics like the SR latch, flip-flops, and counters, with hands-on exercises for the Logic Trainer.
