How to Use
This is an educational tool for building and testing digital circuits. • Drag components from the toolbox onto the workspace to build circuits • Click and drag to connect components with wires - connections snap to input/output pins • Right-click components to delete them or change their properties • Click switches and inputs to toggle them on/off and test your circuit behavior • Watch LEDs and outputs light up to see how signals flow through your circuit • Use "get data" button to export your circuit design as text code • Copy circuit data and use "set data" button to load saved designs • Paste example circuits from tutorials into the text area and click "set data" to load them • Goal: Learn digital logic by experimenting with gates, switches, and components • Try building basic circuits like AND/OR gates, flip-flops, or counters • Test different input combinations to understand how each component responds The simulation runs in real-time, so changes are immediately visible.
