RFID + ESP8266 Based Web Interface System

 

Project Title: RFID_ESP8266_Interface_by_ReponSheikh

GitHub: View on GitHub

📘 Introduction

In this project, I have built a simple yet powerful RFID-based system using the ESP8266 NodeMCU microcontroller. The system reads RFID cards using the MFRC522 module and sends the UID data to a web interface over Wi-Fi. It can be used in access control, attendance tracking, or any kind of RFID-based identification system.


🧰 Components Used

  • ESP8266 NodeMCU (ESP-12E)

  • MFRC522 RFID Reader

  • RFID Tags or Cards (13.56 MHz)

  • Jumper Wires

  • USB Cable and Power Source

🌐 Features

  • Web-based interface to view UID logs

  • Automatic Wi-Fi configuration using WiFiManager

  • LittleFS file system support to store configuration and logs

  • Easy-to-understand code structure with comments

  • Arduino IDE compatible

🔧 How It Works

  1. On boot, the ESP8266 tries to connect to the last used Wi-Fi.

  2. If it fails, it starts as an Access Point for WiFi setup.

  3. Once connected, the RFID reader scans for tags and logs the UID to the web interface.

  4. You can visit the IP address in a browser to view all authorized or scanned UIDs.

🎯 Application Areas

  • Smart Door Lock

  • Employee/Student Attendance

  • IoT Access Control Systems

  • Lab Equipment Authorization

📥 Future Updates

I'm planning to add:

  • EEPROM support to store UIDs permanently

  • Real-time cloud logging

  • Admin panel for adding/removing users

Arduino Programming Tutorial

In this tutorial, we'll cover the basics of Arduino programming, focusing on variable types , functions , function return types , and constant declarations . We will use simple examples to demonstrate how each concept works. 1. Variables in Arduino Variables are used to store data that your Arduino program can use. There are different types of variables based on the data they store. Common variable types: int : Stores integer values (whole numbers). float : Stores decimal numbers. char : Stores a single character. boolean : Stores true or false . String : Stores a sequence of characters (text). Example: int ledPin = 13 ; // Integer variable to store LED pin number float sensorValue = 0.0 ; // Float variable to store sensor value char myChar = 'A' ; // Char variable to store a character boolean isOn = true ; // Boolean variable to store true/false String myText = "Hello" ; // String variable to store a string 2. Constants Constants a...

BJT vs. MOSFET: Understanding the Key Differences

  When it comes to semiconductor devices, BJT (Bipolar Junction Transistor) and MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) are two of the most commonly used transistors. They both play a critical role in amplifying or switching electronic signals, but their underlying principles and applications are quite different. In this post, we’ll explore the fundamental differences between BJT and MOSFET to help you understand their unique features and decide which one to use in your project. What is a BJT? A Bipolar Junction Transistor (BJT) is a current-controlled device that has three terminals: Collector (C) , Base (B) , and Emitter (E) . BJTs can be either NPN or PNP types, depending on the arrangement of their semiconductor layers. BJTs work by using a small current at the base to control a larger current flowing between the collector and emitter. How BJT Works: Current-Controlled : In a BJT, the amount of current that flows from the collector to the emitter is cont...

AI Technology & Medical Service Integration is very Essential for Whom?

For whom AI and medical services have become urgent?  the name of the country, Bangladesh may come upstairs in response to the question. Bangladesh is a very important country in South Asia and most of the sides of this country are surrounded by the Indian border. According to the data published the  year of 2018  in the UK-based medical and public health magazine Lancet, Bangladesh is ranked 133rd among 195 countries in respect of medical and health services. Not only in Bangladesh but financially underdeveloped or developing countries the quality of medical care is weak. Getting these skilled doctors also becomes difficult. On the other hand, Bangladesh's position in the production and export of drugs is at the top of the underdeveloped country, but according to data obtained by 2020, Bangladesh was ranked 72nd in global drug exports. Although Bangladesh has achieved a lot of supremacy in the production of medicine, it is viewed, but it is far behind in medical care. To...
