How to Use
This is a digital circuit simulator for building and testing electronic circuits. • Drag devices from the left toolbox to the workspace on the right • Connect devices by dragging from one connection point to another • Click on an input connection to disconnect it • Drag unwanted devices back to the toolbox to remove them • Click on switches and buttons to activate them and see your circuit operate in real-time Controls: • Double-click device labels to rename them • Double-click library components to view their internal circuits • Ctrl+Click (Mac: Cmd+Click) to switch between circuit view and JSON data view Available components include: • Power sources (DC, oscillators) • Logic gates (AND, OR, NAND, etc.) • Input devices (switches, push buttons) • Output devices (LEDs, 7-segment displays) • Custom library components you can create Goal: Build functional digital circuits by connecting components. Test your designs by activating inputs and observing outputs. Create reusable components using In/Out devices, then save and share your circuit designs using the JSON export feature.
