If you need a guest Wi-Fi network for your home, office, or a coffee shop, you might as well do it with style!
You'll need a Wi-Fi network (:D) and a small computer screen - I used Raspberry Pi Pico with a 64x128 pixels display.
To generate a QR Code that will be recognized by your phone, the string you encode must be in a proper format:
WIFI:S:<SSID>;T:<WEP|WPA|blank>;P:<PASSWORD>;H:<true|false|blank>;
Depending on your screen size, you might have to adjust the SSID + password length, so that QR Code can be displayed on a screen that size.
Depending on which SBC you use, the code to display the QR Code will be different, but for Pico I used MicroPython.

I hope you like it!
