ESP8266 + Python GUI: Serial RS232 Communication Tool

 

Project Title: ESP8266_Serial_Python_GUI_RS232_v3

GitHub Repository: View on GitHub

📘 Overview

This project demonstrates a PC-to-ESP8266 serial communication system using a custom-built Python GUI. The tool is developed for RS232-based command exchange, making it ideal for debugging and interacting with embedded systems like microcontrollers, development boards, and IoT devices.

🎯 Project Goals

  • Establish two-way communication between PC and ESP8266

  • Create a simple Python GUI for sending and receiving serial data

  • Log all serial commands with timestamps

  • Automatically save communication logs in a text file

  • Provide clickable link to the developer’s profile from the GUI



🧰 Tools & Technologies

  • ESP8266 NodeMCU

  • Python 3.x

  • PySerial for COM port communication

  • Tkinter for GUI design

  • RS232 Protocol

  • Windows platform for executable (.exe) build

🌟 Key Features

✅ GUI Interface with Command Input Box
✅ Auto Serial Port Detection
✅ View Incoming/Outgoing Messages with Timestamp
✅ Automatically Saves Logs in Text File
✅ Includes a Clickable Link to Developer's LinkedIn Profile
✅ Easily Build .exe using pyinstaller

🧪 How It Works

  1. Connect the ESP8266 board to the PC via USB.

  2. Run the Python GUI (or compiled .exe).

  3. Select the correct COM port.

  4. Type commands and hit Send – observe real-time communication.

  5. All messages are logged with timestamps and saved.

🛠 Build the Executable

Use this command to create a standalone .exe file from Python:

bash
pyinstaller --onefile --windowed main.py

Note: Install required packages using pip install pyserial if not already available.

📥 Applications

  • ESP8266 Debugging Tools

  • RS232-based Device Configuration

  • GUI for Embedded Device Testing

  • Home Automation Serial Interfaces

  • Custom IoT Serial Terminal

📚 Skills Demonstrated

  • Python GUI Design with Tkinter

  • Serial Communication with PySerial

  • Embedded System Testing

  • GUI-to-MCU Data Transfer

  • Automation with RS232 Protocol

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...
