The best way to learn something is to learn by doing, trying and applying. VET students should do experiments by themselves. For this purpose, the most important educational tools in VET are experimental sets. The aim of project is to make a successful learning and teaching environment for all VET students and teachers, to transfer good practices on ESP32 training. In our project, 4 VET schools will prepare a common ESP32 experimental set and a guidebook to learn and teach ESP32s more easily.
