When the needs of present and future life are examined, 21st-century skills are gaining importance day by day. There are various teaching methods, techniques and aids that support the development of individual skills and characteristics. Coding has also taken its place among these methods and techniques and continues to gain popularity with increasing speed. In this study, the aim was to create a learning environment where pre-service teachers can experience coding practices. In this context, the study aimed to determine the views of pre-service teachers about their experiences regarding Arduino implementations. In line with this purpose, a workshop was designed where Arduino implementations with the mBlock platform included 30 students studying in the department of computer and instructional technologies, science education department and mathematics education department. This study consists of qualitative data in the form of the case study. Research data was collected with a semi-structured interview form that included four open-ended questions. The final form was obtained by receiving expert opinions about the questions. During the interview process, each participant was informed about the interview's purpose and confidentiality and registration permission was obtained. The content analysis method was used in the data analysis process. The research results were discussed in light of the literature and suggestions were made based on the experiences gained for future researchers.
