Overview of this book

This book will start with the fundamentals of C programming and programming topics, such data types, functions, decision making, program loops, pointers, and structures, with the help of an Arduino board. Then you will get acquainted with Arduino interactions with sensors, LEDs, and autonomous systems and setting up the Arduino environment. Moving on you will also learn how to work on the digital and analog I/O, establish serial communications with autonomous systems, and integrate with electronic devices. By the end of the book, you will be able to make basic projects such as LED cube and smart weather system that leverages C.

Understanding OOP better


I know you've probably got a little bit of a headache if you are not familiar with the concept of OOP. Don't worry-keep reading and the idea of OOP will be clear to you soon. Let's start clarifying the situation by looking at an example involving functions.

Imagine a situation where you need to write the following print statements:

Serial.println("My name is John, I am 24 years old and my height 6.1 feet"); 
Serial.println("My name is Tom, I am 26 years old and my height 6.5 feet"); 
Serial.println("My name is Curl, I am 21 years old and my height 5.9 feet"); 

Have you noticed something in this code? The lines are almost similar. The only differences are the names, the age, and the height.

I know what you are thinking: We can make a function with three parameters like the following:

void myFunction(String name, int age, float height) { 
  Serial.println("My name is "); 
  Serial.print(name); 
  Serial.print(", I am "); 
  Serial.print...
