Introduction to Arduino

Introduction to the Arduino Prototyping Board

Arduino prototyping boards have revolutionized the world of electronics and embedded systems by providing an accessible, user-friendly platform for hobbyists, students, and professionals alike. Arduino boards are open-source microcontroller platforms that enable users to create interactive electronic projects with ease. These boards come equipped with a microcontroller and various input/output (I/O) pins, allowing for the connection of sensors, actuators, and other electronic components.

The Arduino open-source system is supported by a robust integrated development environment (IDE) and an extensive library of code examples, making it simple for users to write, upload, and debug their programs. With its plug-and-play functionality, Arduino has become a cornerstone in the maker movement, empowering individuals to bring their creative ideas to life.

Arduino - UNO

The Arduino UNO is the best board to get started with electronics and coding. If this is your first experience tinkering with the platform, the UNO is the most robust board you can start playing with. The UNO is the most used and documented board of the whole Arduino family.

Using the Arduino UNO

Programming: Use the Arduino IDE to write and upload sketches via the USB connection.

Libraries: Utilize built-in and third-party libraries to expand the functionality of the board.

Community: Leverage the extensive Arduino community for tutorials, project ideas, and troubleshooting.

Arduino UNO - Software

The open-source Arduino Software (IDE) makes it easy to write code and upload it to the board. It runs on Windows, Mac OS, and Linux. The environment is written in Java and based on Processing and other open-source software. In order to program the Arduino microcontroller, you need to install the Arduino Desktop IDE ( Integrated Development Environment). The Arduino Software (IDE) allows you to write programs and upload them to your board.

Arduino Software (IDE)

The Arduino IDE - Integrated Development Environment - contains a text editor for writing code, a message area, a text console, a toolbar with buttons for common functions, and a series of menus.

Writing Sketches

Programs written using Arduino IDE are called sketches. These sketches are written in the text editor and are saved with the file extension .ino. The message area gives feedback while saving and exporting and also displays errors. The console displays text output by the Arduino IDE, including complete error messages and other information. The bottom righthand corner of the window displays the configured board and serial port. The toolbar buttons allow you to verify and upload programs, create, open, and save sketches, and open the serial monitor.

Introduction to the Arduino IDE and Sketches

The Arduino Integrated Development Environment (IDE) is the primary interface for writing, compiling, and uploading code to your Arduino board. It uses the concept of a sketchbook, a standard place where your programs (or sketches) are stored.

Basic Structure of an Arduino Sketch

An Arduino sketch typically consists of two main functions:

1. setup():

void setup() {

  // initialize digital pin 13 as an output.

  pinMode(13, OUTPUT);

}

2. loop():

void loop() {

  digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level)

  delay(1000);            // wait for a second

  digitalWrite(13, LOW);  // turn the LED off by making the voltage LOW

  delay(1000);            // wait for a second

}
