Article By: Repon Sheikh,  LinkedIn Account The ESP8266 is a powerful and popular Wi-Fi enabled microcontroller, but its true potential is unlocked when you can run multiple processes simultaneously. This is where a Real-Time Operating System (RTOS) becomes invaluable. An RTOS allows a single processor to handle multiple tasks concurrently, which is crucial for applications that need to perform various functions like communication, sensor reading, and user interface updates without interruption. This article introduces a straightforward project that serves as a perfect entry point into the world of RTOS development on the ESP8266. Using the FreeRTOS SDK, a widely adopted open-source RTOS, this example demonstrates how to create and manage two independent tasks. The full source code for this project can be found on GitHub: ESP8266_Multi_Task_RTOS_Example . The Project Explained At its core, this project defines two distinct tasks: blink_task : This task is responsible for the class...

  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 On boot, the ESP8266 tries to connect to the last used Wi-Fi. If it fails, it starts as an Access Point for WiFi setup. Once connect...
