Gate theory
An AND gate is a basic digital logic gate that produces a high output only when all of its inputs are high.

Understand AND gate logic through live input-output behavior
The AND gate behaves like a strict condition checker: if A and B are both 1, the output is 1; otherwise the output remains 0. The simulator helps students connect symbols, Boolean expressions, truth tables, and circuit output without needing physical hardware.
Understand the Boolean expression and truth table of an AND gate.
Predict the output for every input combination.
Connect AND logic with conditions used in circuits and programs.
Use the simulator to compare theory with live input changes.
Where this gate is used
- Digital enable circuits
- Conditional control systems
- Arithmetic circuits and adders
- Computer science logic practice
How the interactive lab works
Open the AND gate lab, toggle the binary input controls, and watch the output update immediately. The visual circuit and truth table make each Boolean result easier to verify.
