The core part of the automatic retractable door is the single-chip microcomputer, which is connected to the external inverting Sanjie buffer and the electrode open reverse door to obtain the dynamic short code to obtain the signal. Because the microcontroller does not have a large amount of computing data and cached data, it can always maintain fast operation. After high-speed calculation and processing, the large disk converts the signal into an analog signal and outputs it, and the motor starts to run after getting the driving signal, and the automatic retractable door can be opened and closed by generating machinery.
