What is the Logic Circuit Simulator?
This tool is an online simulator that allows you to intuitively build and test digital logic circuits in your browser. It supports a wide range of components, from basic logic gates (AND, OR, NOT, etc.) to flip-flops essential for memory circuits. It is ideal for school assignments, electronic project preparation, or as a learning tool to deepen your understanding of digital logic.
How to Use
- Placement & Movement: Drag buttons from the top-left panel or click them to add elements. Once placed, you can move blocks freely by dragging them.
- Wiring: Click and hold the "●" terminals on either side of an element, then drag to a terminal on another element to create a connection.
- Toggling Input: Hold the Shift key and click a SWITCH to toggle its ON/OFF state.
- Deletion: Right-click an element or a wire to delete it individually.
- Navigation: Right-drag the background to pan the view, and use the mouse wheel to zoom in/out.
- Fullscreen: Click the "FULLSCREEN" button in the bottom-right to maximize the workspace.
Key Features
- No Installation Required: Runs entirely in your browser, accessible from any OS.
- Completely Free & No Sign-up: All features are available for free. You can also save and load your design data.
- Real-time Simulation: Logic changes are reflected instantly, and the state of the wires is visualized by color.
- Secure Design: All processing is done locally in your browser; your circuit designs are never sent to a server.
Basic Steps to Get Started
- Select the elements you want to use (such as SWITCH or AND gates) from the "IO / Gates" panel and place them in the workspace.
- Connect the elements with wires and check if the intended logic is functioning correctly.
- Once your circuit is working, click "SAVE" to download it as a JSON file.
- You can resume your work anytime by clicking "LOAD" and selecting your saved file.
Frequently Asked Questions (FAQ)
A. Yes, basic combinational and sequential circuits (flip-flops, etc.) will work without issues. However, for extremely large circuits, performance may depend on your browser's processing speed.
A. Clicking "SAVE" downloads the data as a file. Please check your browser's download permission settings.
A. The UI is designed for mouse operations on a PC. While you can view it on a smartphone, we recommend a PC environment for precise tasks like wiring and moving elements.
