AND Gate Using Arduino Nano

The objective of this project is to demonstrate the working of an AND logic gate using an Arduino Nano and two push buttons.

DESHBOT SHIELD

UNO NANO

INBUILD LED

INBUILD SWITCHES

The two buttons represent the two inputs of the AND gate:

1. Button A → Input A
2. Button B → Input B
3. LED → Output

The Arduino reads both button states and performs the AND operation.

The LED turns ON only when A and B are both HIGH (pressed).

Logic

A AND B → LED

This project demonstrates how an Arduino Nano can reproduce the behavior of an AND logic gate using two push buttons and an LED. It helps explain the relationship between digital inputs, Boolean logic, and digital outputs.
