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.

Adding conditions in the code

Because I studied Biology and have a Master's diploma, I'm familiar with organic and living behaviors. I like to tell my students that the code, especially in interaction design fields of work, has to be alive. With Arduino, we often build machines that are able to "feel" the real world and interact with it by acting on it. This couldn't be done without condition statements. This type of statement is called a control structure. We used one conditional structure while we tested our big code including variables display and more.

if and else conditional structure

This is the one we used without explaining. You just learned patience and zen. Things begin to come, right? Now, let's explain it. This structure is very intuitive because it is very similar to any conditional pseudo code. Here is one:

If the value of the variable a is smaller than the value of variable b, switch on the LED. Else switch it off.

Now the real C code, where I simplify the part about the LED by...
