The code in this repo is the results of a blog series I wrote about building a captive web portal for a Wemos D1 Mini using MicroPython. You can find the articles here:
Copy the .py and .html files to your ESP8266 board. If you already have a main.py file, then just copy the contents of
the main.py file from this repo. There's only a couple of lines there.
Instantiating a CaptivePortal and calling its start() method will turn on your MCU's WiFi access point, and you can
then connect to it and input your home WiFi credentials. Once you do, the MCU will turn off its AP, and connect to your
home WiFi instead.
This is not really a standalone project, but rather a bit of useful functionality that I drop into other projects I make so that if I send one to someone else, I don't need to hardcode their home WiFi credentials to get the thing to work. Instead, they can easily enter their own WiFi SSID and password to allow the device to connect and start doing whatever it's supposed to be doing.
