This thesis explores the possibility of integrating everyday programs into computer science education, aiming to enhance students’ computational thinking and programming skills while aligning with the objectives of the Computer Science Curriculum for primary and secondary schools. The Arduino platform was chosen for this exploration due to it being rich in hardware components, which increase creativity in project development. Additionally, the platform is supported by a strong online community, thus greatly facilitating working with all of its components. The programs were developed on the Arduino UNO board, using free software tools Arduino IDE and Tinkercad. The core of this thesis and the elaboration of programs are covered in five distinct activities suitable for high school students. These activities include controlling lights, simulating traffic lights, a digital piano, a burglar alarm system and automatic sliding doors. Working with Arduino boards requires an understanding of basic physics concepts, such as electrical circuits and Ohm’s law, thereby providing opportunities for interdisciplinary connections between Physics and Computer Science in teaching. This thesis emphasizes the value of learning through hands-on program creation in computer science education. By engaging in these activities, students not only refine their programming skills but also gain invaluable experience due to the physical construction of programs. Observing visual results of their work deepens students' understanding and promotes critical thinking, as well as the development of analytical skills in project planning.
