eWeLink WiFi Light Switch

This is a handy indoor light switch for college students. The schematic, source code, and PCB are all open-sourced. It allows multiple people to remotely control a single switch outdoors, and also supports infrared remote control up to ten meters. It can also be connected to
a Xiao Ai speaker for control. I initially saw a similar product on Taobao and thought it was very creative, so I quietly noted it down. I wanted to buy one, but the finished product was expensive and couldn't connect to the network, so I decided to make one myself.
 
The simplest components are: an eMicroLink PSF-B04 module, an STC8h1K08, and an SG90 servo motor, forming a four-channel independent servo motor with angle data retention even after power loss.
The servo angle can be modified using a host computer serial port assistant or fine-tuned using a serial encoder control board. Operation can be seen in the video on the homepage.
