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

Connect the ESP8266 board to the PC via USB.
Run the Python GUI (or compiled .exe).
Select the correct COM port.
Type commands and hit Send – observe real-time communication.
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.

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...

Embedded system programming & development interest is becoming more popular

Over the years there has been a growing interest in embedded systems development and programming as part of science technology and computer research. Due to the obligation to present a project or research in science in many schools, colleges, or universities, this subject is becoming necessary and acceptable day by day. In most cases, science projects are gaining importance as electronics and embedded system programming. This is because of their easy availability and the availability of lots of information on the Internet. photo: Arduino board, an example of an embedded board Arduino Board is a top choice for beginners of electro-embedded designers because of this less complexity and availability of lots of resources online. easy and attractive beginning to an embedded programming platform is Arduino. to be continued... writer: Repon Sheikh
