The course is appropriate for classroom teachers of every school level. There is no need of prior knowledge of the Arduino board and programming methods, as the course starts introducing everything from scratch. It provides educators with the knowledge and skills necessary to initiate programmes using Arduino, making basic connections and wiring on a typical breadboard, writing programmes using the Arduino IDE and some other block-based programming platforms. There is a basic introduction to widely-used sensors and the course ends with the creation of simple stand-alone projects that can also be used in larger projects or as teaching examples in the classroom.
