The Arduino is a small computer that you can program to read information from the world around you and to send commands to the outside world. All of this is possible because you can connect several devices and components to the Arduino to do what you want. The Arduino is the best way to get started into to the world of digital electronics. To get started with Arduino download our PAID eBook – Arduino Projects for Beginners (contains 27 DIY projects for beginners).
