What is Arduino?

Arduino is an open-source electronics platform based on easy-to-use hardware and software. It consists of a microcontroller board and an integrated development environment (IDE) that allows you to write, compile, and upload code to the board. Arduino boards can read inputs from sensors, control outputs like motors and lights, and communicate with other devices, making them ideal for creating interactive projects.

Key Components of an Arduino Board

• Microcontroller: The brain of the board, typically an ATmega328 or similar chip.
• Digital and Analog Pins: Used to connect sensors, actuators, and other peripherals.
• Power Supply: Can be powered via USB or an external power source.
• USB Interface: For programming and communication with a computer.
• Reset Button: Allows restarting the program running on the board.

Getting Started with Arduino Programming

Programming Arduino involves writing code in the Arduino IDE using a simplified version of C++. The code is structured in two main functions: setup() and loop(). The setup() function runs once when the board is powered on or reset, while the loop() function runs continuously, allowing the Arduino to perform tasks repeatedly.

Basic Arduino Sketch Example

Here is a simple example to blink an LED connected to digital pin 13:

void setup() {
  pinMode(13, OUTPUT);
}

void loop() {
  digitalWrite(13, HIGH);
  delay(1000);
  digitalWrite(13, LOW);
  delay(1000);
}

This code sets pin 13 as an output and toggles it on and off every second, causing the LED to blink.
