Logic gates & circuits

Explore AND, OR, NOT, and XOR with large switches and a lamp. Then add your own inputs and gates, drag wires between ports, and connect the circuit to one shared output. Blocks arrange themselves automatically, while a separate settings panel keeps controls within reach. The graph runs from left to right on a computer and top to bottom on a phone.

You will get a feel for

1. Discover how AND, OR, NOT, and XOR respond to their inputs.
2. Combine gates and follow signals through a circuit.
3. Connect simple logical rules to the building blocks of a processor.
