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.

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...

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...

Troubleshooting an EEPROM Write Issue in a Microcontroller – A Real-World Debugging Experience

 Troubleshooting an EEPROM Write Issue in a Microcontroller—A Real-World Debugging Experience 🔧 Problem Statement While working on an embedded system at an R&D firm, I encountered a puzzling problem with EEPROM data writing. The EEPROM write operation was perfectly simulated, but when the compiled HEX file was uploaded to the actual microcontroller, the written data became unrecognizable. 🧪 Initial Assumptions At first, I assumed there might be a logical bug in my code. However, after carefully reviewing my EEPROM write functions and re-running simulations multiple times, everything appeared to be correct. 🛠 Step-by-Step Debugging Process 1. Verification via Custom Tool To confirm whether the EEPROM was actually writing incorrect data, I built a simple tool that could: Read the EEPROM data from the microcontroller Convert and display the raw bytes into human-readable formats like integer and character Upon reading the EEPROM content using this tool, I conf...
