Arduino is a family of single-board microcontrollers, intended to make it easier to build interactive objects or environments. What the Arduino platform has done is to take what was once a fragmented and expensive market for robotics and microprocessors and become the major platform, largely by virtue of much lower cost and ease of use, leading to higher volume and popularity, and community support behind it. Arduino has made it simple to program their boards with any computer via USB and simple to integrate with a wide array of sensors and devices. The Arduino is great for hobbyists, prototypers, and people just starting out in robotics because of its low cost, ease of use, and large following online. It’s easy to learn and teach people to be able to do basic things with the Arduino, yet it’s capable enough to do fairly sophisticated things if you as a developer have the capability to take advantage of it. 

It’s allowing people to develop projects inexpensively to build and control their own devices, such as sensors that send data to the Internet and control systems for all kinds of things. It’s also reducing the cost of development by allowing companies to develop prototypes much more quickly and with less initial investment. 

The Arduino is going to enable businesses to do things that aren’t commonly done today with remote sensor networks. This could lead to entirely new control strategies for making buildings more comfortable, saving energy, and reducing maintenance costs for equipment. The Arduino is going to allow businesses to develop products that are more easily upgradeable. 

Arduino is backbone for many future technologies. Already 3D printers, DIY Drones etc. are open for the public to prototype and design. The main intention of this book is to give an introduction to the world of Arduinos. I’ve tried my best to keep the book as simple and informative as possible.
