The fact that microcontrollers are so common is the major reason you should be familiar with them. Microcontrollers, on the other hand, are a lot of fun to use and design with. You can get things up and running quickly that would have taken considerably longer in the past. You may also have a lot of fun while doing it, and what would life be without a little fun?
The possibilities for what you can accomplish and create with them are endless. The computer, it has been said, is the ultimate tinker toy: you can utilize it in an infinite number of ways to improve your profession, learning, pastime, or social life. Microcontrollers are valuable because they enable you to extend the benefits of computer into the real world. Without realizing it, you probably already have a lot of microcontrollers. They're in almost all of the appliances and devices in your environment. Anyone who wants a thorough understanding of how modern products-from vehicles to cellphones to toys, must have a working knowledge of microcontrollers.
In this book, first we have explained all the things you need to know about micro-controllers, from its types to its features. This information would be enough to get you started with building your own projects using micro-controllers. Then in the following chapters we have given the basic introduction of two of the most commonly used micro-controller platforms for learning purposes i.e. arduino and raspberry pi. These introductions would be enough for you to get started with them and build your first project with them.
