February 8:
You can open the door through the Dian Deng Technology APP !
The door can also be opened through 32 hotspot LAN !
The lighting technology displays battery power , percentage , and charging status !
First generation !
The optocoupler cannot display the charging status properly!
Unable to pull the IO port high!
The finished product pictures and 3D model pictures are the second generation !
The charging state defect of the first generation has been improved!
A resistor voltage divider is used to pull the IO port high !
Charging status can be displayed normally !
And added LED light prompt silk screen!
Under normal operation, all LED lights are off !
Increase the usage time during power outage !
Heating prompt symbols in the charging, boosting, and voltage stabilizing areas!
February 9:
Added one-click network configuration function!
You can configure the network by scanning the QR code !
You can connect to the Internet in different WIFI environments without modifying the code !
February 16th:
Draw the access control housing model !
Easy to fix the access control installation to the door!
The finished product is as follows:
The internal diagram is as follows:
The 3D model diagram is as follows:

This project refers to this project: https://oshwhub.com/Aknice/esp12-zui-xiao-ji-tong-ban Thanks to every open source author!
This reference project has an ESP12 memory overflow !
A problem that prevents lighting technology from being used!
Replaced MCU: ESP12 with ESP32!
Optocoupler feedback charging is replaced by resistor voltage dividing feedback charging!
The servo is integrated into the PCB !
The steering gear was changed to MG90S !
The program has been modified according to the changes in the PCB!
The TTL-USB download function has been removed !
Added 3D models of PCB components !
Join the one-click network configuration program !
Made a 3D model shell !
