Door access control witch E-paper QR-code reader

Because I've bought e-paper for many years,

I still don't know how to use it. Until a few days ago,

when I found it, it still showed the old message

that I had tried for a long time(5 year). So I came up with the idea of this project.

STEP1: E-pager Gen QR Code for Test

STEP2: Assembly board for Test

Because originally using ESP32CAM a problems with slow
reading In low light,Therefore finding a device
that can be used instead

QR Code scanner : Cod fly aibcy yhd -9800

RS232 Pin out
