The AND module is a logic gate with two inputs and one output. In order for the AND gate to output an ON signal, both inputs need to be ON at the same time. When this happens, you are able to activate any output module like an LED, a DC motor, or a buzzer. The AND module is a good option for projects in which you want two actions to trigger another.
In the truth table ON = 1 and OFF = 0.
Real World Example:
The AND function can be demonstrated by thinking about a door with two locks. The only way to get through this door is to unlock lock 1 AND to unlock lock 2. Otherwise you will be stuck outside.
