In recent years, with the promotion of maker education, new breakthroughs have been brought to current high school information technology teaching. Based on the characteristics of the information technology discipline, teachers should fully recognize the significance of maker education, integrate various teaching resources, focus on cultivating students'' innovation and practical operation abilities, and comprehensively promote their core literacy in the information technology discipline. In this context, this article revolves around the theme of "The Big Future of Small Home Appliances", using PBL project-based learning to first propose problems, then analyze them, and ultimately learn knowledge during the process of solving problems. The project implementation content takes the construction of an infrared remote control fan system and the use of open-source hardware and temperature sensors to build a temperature control fan system as an example, leading students to practice maker activities such as "connecting infrared emission tubes, receiving tube circuits, testing infrared remote control fans, and transforming temperature control fans". During the activities, students will understand the working principle of sensors, experience the fun of programming, and experience the intelligent processing of information. This paper explores innovative strategies for project-based teaching of high school information technology PBL under the background of makers, providing reference for high school information technology teaching.
