The Fourth Industrial Revolution is approaching. In the era of the Fourth Industrial Revolution, artificial intelligence is expected to transcend humanity in many fields due to its superior learning ability. For this reason, humanity is more important than creativity in solving problems, and creativity in determining what problems to solve and education in how to direct artificial intelligence to solve problems. The basis of how to direct artificial intelligence to solve problems can become a program. Programs have invisible properties compared to hardware. Because of this, it has very high barriers to entry for the first time. Physical computing is the physical thing that inputs and outputs are visible, making it easy for people to understand the program for the first time. Physical computing is used as a learning tool for elementary and middle school students. In this paper, we propose a method to design a parish for teaching physical computing. In order to design the parish, we first analyzed the core technology of the program and presented an example for the preparation of the teaching plan. The parish was designed according to the analysis, and the diocese consisted of the Arduino and the input / output sensor smartphone.
