In response to the current shortcomings of teaching circuit boards for microcontrollers on the market, such as excessive functions, high prices, and unclear experimental phenomena, this article starts from the “basic” perspective and uses peripherals such as buttons, buzzers, LED lights, digital tubes, LCD screens, and computer displays that are most closely related to human senses to strip the basic functions of microcontrollers from these circuit boards. Using touch (buttons) as a medium, the response made by microcontrollers is displayed through auditory, visual (sound, light, screen, etc.) and other sensory methods. On the premise of reducing purchase costs, increase the user’s interest in learning microcontrollers and enhance the learning effectiveness of learners.
