Introduction to Arduino:

Arduino is an open-source electronics platform that is popular for creating interactive projects. It consists of both hardware and software components, making it accessible for beginners and versatile for advanced users. Below is an overview of Arduino, its components, and a simple example project to get you started.

1. Arduino Board:

• The heart of the Arduino system is the Arduino board. It typically contains a microcontroller, input/output pins, USB interface, and other components.

2. Arduino IDE:

• The Arduino Integrated Development Environment (IDE) is where you write, compile, and upload your code to the Arduino board. It supports a simplified version of C++ programming.

3. Programming Language:

• Arduino programming is done using a simplified version of C++, making it accessible for beginners. You write sketches (programs) to control the behavior of the Arduino.

4. Shields:

• Arduino shields are additional boards that can be mounted on top of the Arduino to provide extra functionality. Examples include motor shields, display shields, and communication shields.

Basic Arduino Components:

1. Microcontroller:

• The brain of the Arduino board, responsible for executing the program and controlling attached devices.

2. Input/Output Pins:

• Used to connect sensors, actuators, and other devices to the Arduino. Pins can be either digital or analog, and they support input and output operations.

3. USB Interface:

• Used for uploading sketches to the Arduino board and for serial communication between the board and your computer.

4. Power Supply:

• Arduino boards can be powered via USB or an external power source. Some boards also have a built-in voltage regulator.

Simple Arduino Project: Blinking LED

Components Needed:

• Arduino board
• LED
• Resistor (220 ohms)
• Jumper wires

Circuit Connection:

1. Connect the longer leg of the LED (anode) to digital pin 13 on the Arduino.
2. Connect the shorter leg of the LED (cathode) to the ground (GND) on the Arduino via the resistor.
