Maker education is the process of implementing what is learned through SW education by using tools such as Arduino, Robot, 3D printer, VR, etc., and making it into reality. In other words, maker education is a teaching and learning method that realizes SW education. In this study, we propose a case study on maker education based on computational thinking. To this end, we propose a training case for developing devices for real life using Arduino input / output computing systems and digital logic circuits. Applying the results of this research to various subjects, it can be used to combine maker education with computational thinking process and systematize maker education method.
