The main control chip STC89C52 of this MCU-based intelligent window control system chose option 2 because it has a serial port for downloading burning programs, which is extremely convenient. He is very friendly to beginners. It's easier to start than the STM32 microcontroller. And can request a large amount of progressive learning information through the network. The operating voltage is about 5V. There is no need to configure a voltage regulator circuit. Therefore, the design of this system selects STC89C52 single-chip microcompute
