C Programming for Arduino

Overview of this book

Physical computing allows us to build interactive physical systems by using software & hardware in order to sense and respond to the real world. C Programming for Arduino will show you how to harness powerful capabilities like sensing, feedbacks, programming and even wiring and developing your own autonomous systems. C Programming for Arduino contains everything you need to directly start wiring and coding your own electronic project. You'll learn C and how to code several types of firmware for your Arduino, and then move on to design small typical systems to understand how handling buttons, leds, LCD, network modules and much more. After running through C/C++ for the Arduino, you'll learn how to control your software by using real buttons and distance sensors and even discover how you can use your Arduino with the Processing framework so that they work in unison. Advanced coverage includes using Wi-Fi networks and batteries to make your Arduino-based hardware more mobile and flexible without wires. If you want to learn how to build your own electronic devices with powerful open-source technology, then this book is for you.

Making smart loops for repetitive tasks

A loop is a series of events repeating themselves in time. Basically, computers have been designed, at first, to make a lot of calculations repeatedly to save human's time. Designing a loop to repeat tasks that have to be repeated seems a natural idea. C natively implements some ways to design loops. Arduino core naturally includes three loop structures:

  • for

  • while

  • dowhile

for loop structure

The for loop statement is quite easy to use. It is based on, at least, one counter starting from a particular value you define, and increments or decrements it until another defined value. The syntax is:

for (declaration & definition ; condition ; increment) {
// statements

The counter is also named index. I'm showing you a real example here:

for (int i = 0 ; i < 100 ; i++) {

This basic example defines a loop that prints all integers from 0 to 99. The declaration/definition of the integer type variable i is the first element of the for structure...
