Abstract
That is the continuation of the experimentation developed in a First Level Secondary School (grades 6 to 8) on how to start using ARDUINO. The first experimentation was presented at DIDAMATICA 2016. This year, projects have been doubled and reiterated, better focusing on learning processes. After noticing the presence of “misconceptions”, a strategy has been elaborated, in order to go beyond them and reach a “conceptual change” able to help a more informed planning through ARDUINO.
