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.

C standard mathematical functions and Arduino

As we have already seen, almost all standard C and C++ entities supported by the compiler avr-g++ should work with Arduino. This is also true for C mathematical functions.

This group of functions is a part of the (famous) C standard library. A lot of functions of this group are inherited in C++. There are some differences between C and C++ in the use of complex numbers. C++ doesn't provide complex numbers handling from that library but from its own C++ standard library by using the class template std::complex.

Almost all these functions are designed to work with and manipulate floating-point numbers. In standard C, this library is known as math.h (a filename), which we mention in the header of a C program, so that we can use its functions.

Trigonometric C functions in the Arduino core

We often need to make some trigonometric calculations, from determining distances an object has moved, to angular speed, and many other real-world properties. Sometimes...
