Internet of things, intranet, open source, programs, future ahead. Arduino, a small test device for learning and testing. I was interested in a subject in a course on studies. Hence this picture. With the help of them and programming languages, we do great things, we create smart things that surround us, we create the future. The basic idea is to make life easier and save money of course with other savings such as electricity, water, etc. For example. smart heating or cooling devices that fully adapt to your needs and habits, the current climate, while saving energy and so on. Think of a simple programmer that takes care of watering your flowers? This would mean that he recognizes exactly when the earth no longer has the required humidity level and knows how much water is needed at that moment, say. So are thousands of other options. Do you have an idea which smart device would benefit you?
