This post will discuss the code of our ESP32 Keypad Database Security System and how we will control our doorlock using the keypad. This will also explain how it calls our REST API server so that we can access our database interface.
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 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
