Arduino is a platform that makes it possible to put your own ideas into practice. On the one hand Arduino consists of a circuit board with a microcontroller, i.e. a kind of mini PC. On the other hand Arduino consists of software code to develop program logic. Because of its simple hardware, Arduino is very inexpensive at just a few euros.
For some years now I have been privately in contact with “the little guys” and have implemented some projects and would like to give back some ideas to the community.
