Logic gates and truth tables – AND, OR, NOT, NAND, NOR, XOR, half adder

Design & TechnologyElectronics & MicrocontrollersAges 17–18

Pick a logic gate, flip the input switches (0/1), and watch the logic level travel along the wires to the output LED; the truth table beside it highlights the current row, together with the Boolean algebra expression. Half adder mode combines an XOR and an AND gate to compute the sum S and carry C of two bits; the Auto Run button steps through every input combination in turn.
