[Internet of Things] Smart WIFI switch +664942A

# Introduction to the design and production of the smart WIFI switch development board, using the Hongmeng Hi3861 chip combined with the servo to realize WIFI remote control of the physical switch in the home or dormitory, as well as the development and utilization of other redundant modules and microcontrollers on hand (~~Then I found that the microcontroller did not know I'm really ashamed of where I lost it, but the Hongmeng chip on this board can be used normally~~). The board is equipped with over-current protection, serial port programming, battery interface and other additional functions. # There is nothing much to say about welding and welding on the actual picture, just weld directly and you’re done. Below is the actual picture. ![klx.png] Regarding the things that were not soldered, I can only say that I didn’t check my inventory when I was drawing the board. It seemed that the things were not around, so I was confused, but it didn’t matter. After all, as long as the Hongmeng chip Many functions can be achieved. # Code development and demonstration video This time the code development is directly based on what the teacher used during the live broadcast. The language is python and the development tool is pycharm. It also controls the servo. It is basically the same as what was taught in the live broadcast class and will not be released here. . Below is a demo video.
