Massimo Banzi, co-founder of the Arduino project, wrote the first edition of Getting Started with Arduino in 2008 as a short, approachable introduction. By the 4th edition (released around 2016–2017), co-author Michael Shiloh had helped expand it to cover newer boards (Uno, Leonardo, Yun, and early MKR series) plus more on electronics fundamentals.

This book became a classic “Day 1” resource for makers, students, and hobbyists. AppNee.com.Getting.Started.With.Arduino.4th.Edi...

Arduino offers a variety of boards. The most common one for beginners is the Arduino Uno. It's essential to select the right board for your project. Massimo Banzi , co-founder of the Arduino project,

int led = 13;
void setup()  pinMode(button, INPUT_PULLUP); pinMode(led, OUTPUT); 
void loop() 
  if (digitalRead(button) == LOW) digitalWrite(led, HIGH);
  else digitalWrite(led, LOW);
