In this article we are going to program our Arduino RFID Database Security System. We will configure the Arduino to read the MFRC522 RFID Reader and retrieve the RFID code. The RFID code is then sent thru the ESP8266 ESP-01 through serial communication.
This article describes how to design an Arduino RFID Security System that uses the ESP8266 ESP-01 to communicate with the database
This project connects the Arduino Project to the internet using the ESP8266 ESP-01 microcontroller. They communicate using the serial interfaces and passes data as JSON object
