It is like a super tiny computer that you can program to do things, and it interacts with the world through electronic sensors, lights, and motors. It was made to be easy to use and the language you use to tell it to do stuff is simple. Plants keep dying? Use a moisture sensor to tell the Arduino to tell the clamp on a water tube to open for 3 seconds. With these little devices and some pre-written codes you can dream up all kinds of applications to make life more fun for both you and your plants. Many tinkerers, artists and at-home engineers have been using the boards to build so called “smart” machines that can sense when an event happens and tell motors or servos to take action. This technology is at the heart of the interconnected Internet of Things (IoT)in which objects and data can be joined together into useful automation. Science fiction? Science fact?
