This post explores how to get started with the Arduino support for MicroPython using the Arduino Lab for Micropython
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
