The 21st-century challenges have established changes in education's prospects. In this vein, the current action-research followed the three steps (planning, implementation, evaluation) of an interdisciplinary project which explores the pedagogical impact of its application in the field of STEM education. The three stages of the project are an overview of an internet-of-things platform called Fielduino – Digital Farming. This platform constitutes a prototype for a do-it-yourself (DIY) construction and maintenance of a system which is capable of applying new technologies. The research was conducted in a provincial Institute of Vocational Education. The participants were a group of five trainees. The research tool employed was participatory observation. The research results highlighted that the current project positively influenced computational thinking, soft skills development, and the trainees' engagement with STEM education.
