Where is RFID technology used?

The most common RFID applications in hospitals are inventory tracking, control access, staff and patients tracking, tracking tools, tracking disposable consumables, tracking large/expensive equipment, laundry tracking, etc.

What is Nodemcu ESP32?

NodeMCU is an open source Lua based firmware for the ESP32 and ESP8266 WiFi SOC from Espressif and uses an on-module flash-based SPIFFS file system. NodeMCU is implemented in C and is layered on the Espressif ESP-IDF. Support for the new ESP32 WiFi/BlueTooth SOC from Espressif is under way.

Can a NodeMCU interface with a RFID reader?

In this tutorial we will learn How to interface NodeMCU with RC522 RF ID Reader using Arduino library for MFRC522 and other RFID RC522 based modules.

How does Arduino read and write RFID cards?

This library read and write different types of Radio-Frequency IDentification (RFID) cards on your Arduino or NodeMCU using a RC522 based reader connected via the Serial Peripheral Interface (SPI) interface. What is RFID? Radio-frequency identification ( RFID) uses electromagnetic fields to automatically identify and track tags attached to objects.

How can I change the frequency of my NodeMCU?

To do this, go to Tools> Board and select the NodeMCU 1.0 card. You should then adjust the settings, as you will see at the bottom of the image and in the upper part of the code. By default, the NodeMCU operates at a frequency of 80 MHz. It can be set to 160 MHz frequency if desired.

How is the miso pin connected to the NodeMCU?

The MISO pin of the RFID module is connected with the D6 pin of the Nodemcu module. The MOSI pin of the RFID reader is connected with the D7 pin of the Nodemcu ESP8266. The SCK pin of the RFID module is connected with the D5 pin of the Nodemcu and
