Public libraries offer workshops to spread knowledge beyond the books they offer. Public libraries in Catalonia have been offering programming activities for beginners organized by Code Club Catalonia for years, where college students voluntarily teach programming to primary and secondary school students through projects and activities that the organization Code Club Catalonia makes available to educators. This paper presents my experience leading a group of students in this activity and the importance of workshops in public libraries to promote the use of these and to bring them closer to children and youngsters, based on statistical data, testimonials from the students I had and my own experience.
