Guide for the development of STEM applications and educational activities with Arduino. In today's era, wherever we look, we will find hidden mechanisms that control certain conditions and act accordingly. These mechanisms are usually based on microcomputers or microcontrollers and are found in household appliances, personal electronic devices that we use daily (digital watches, mobile phones, tablets, etc.), and even in our cars, which in some cases can park or even drive "on their own".
All these things seem wonderful because they seem to happen on their own. However, if we think about it a little, we will realize that behind them lies a human mind, which has given the appropriate commands to these mechanisms to act in this way.
The constructions that we can create with Arduino are many and for various purposes. Hobbyists can build remote-controlled cars, students can create various arrangements that can take measurements, turn on lights when the brightness in the room is low, activate mechanisms, and many more.
The book you are holding follows the teaching method of the spiral arrangement of the material, as formulated in 1960 by the American psychologist Jerome Bruner. It contains a plethora of examples, most of which can be practically implemented, thus giving the reader the opportunity to familiarize themselves with the Arduino C programming language until they are able to create their own applications. It is suitable for beginners as well as advanced users, for middle and high school students as well as students of higher education institutions, for hobbyists as well as professionals.
