Electronic Circuit Simulator

Circuit Simulator Screenshot Welcome to the documentation for the Electronic Circuit Simulator, a simple SFML-based project that visualizes the behavior of basic electronic and physics concepts such as resistance, current, and power using real-time rendering.

⚙️ Setting Up the Project (Visual Studio + SFML)

Follow these steps to build and run the simulator on Windows:

  1. Install Visual Studio 2022 (with C++ Desktop Development tools).
  2. Download and install SFML 2.6+.
  3. In your Visual Studio project:
  4. Add SFML include and library paths (Include and Lib folders).
  5. Link the required SFML libraries:
    sfml-graphics, sfml-window, sfml-system.
  6. Copy the SFML bin DLLs to your project’s executable directory.
  7. Build and run the project.

💡 What is SFML?

SFML (Simple and Fast Multimedia Library) is a C++ library for graphics, audio, and input handling.
It allows developers to easily create 2D visualizations, games, and interactive tools.

This project uses SFML to render electronic circuit diagrams and visualize the current and voltage distribution dynamically.

🧩 Project Idea and Code Overview

The project demonstrates how basic electrical circuits — especially series-parallel resistor networks — can be visualized dynamically using C++ and SFML.

Core Functionality

  • The user enters resistor values and configuration (series and parallel).
  • The program calculates:
  • Equivalent resistance
  • Total current and voltage
  • Individual resistor current, voltage drop, and power
  • Results are displayed in both text and graphical form.

Main Components

  • main.cpp: Handles input/output, performs calculations, and launches visualization.
  • resources.h / resources.cpp: Handle data storage, calculations, and all SFML rendering logic.

🧠 The visualization window shows resistor groups as nodes and connections, with interactive data overlays.

🧪 Demo Implementation

Here’s a video of the running simulator:

🚀 Running the Executable

  1. Download the ZIP file (same name as repository) from the project’s main directory.
  2. Extract it into any folder.
  3. Run the exe file:

(Currently supports Windows only.)

No installation or configuration needed — everything is self-contained.
