Please note that the circuit above just contain necessary items for the project to function. To program it, you have to connect a FTDI or USB to TTL converter. Then, reset with IO0 pulled down to enter program mode. After uploading code, reset again.
Removed due to bugs.
This is a modified version of the official access control example.
- Records stored in ESP8266 SPIFFS as a JSON file.
- Using UID to identify different RFID cards.
- UID are SHA1 hashed and then stored.
- Compare hash to identify users.
This is an enhanced version of V2 with mobile app integration In progress...
V3 in progress...
