C Programming for Arduino

By: Julien Bayle

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.

Pushing the button


We are going to have fun. Yes, this is the very special moment when we are going to link the physical world to the virtual world. Arduino is all about this.

What is a button, a switch?

A switch is an electrical component that is able to break an electrical circuit. There are a lot of different types of switches.

Different types of switches

Some switches are called toggles. Toggles are also named continuous switches. In order to act on the circuit, the toggle can be pushed and released each time you want to act and when you release it, the action continues.

Some others are called momentaries. Momentaries are named push for action too. In order to act on the circuit, you have to push and keep the switch pushed to continue the action. If you release it, the action stops.

Usually, all our switches at home are toggles. Except the one for the mixer that you have to push to cut and release to stop it, which means it is a momentary.
