5. Simple DFA Select “Finite Automaton”

6. Adding Nodes Click this here button

7. Adding Nodes Now click on the workspace to add it

8. Setting the initial state Click the “attribute editor” button

9. Setting the initial state Right click on the node and select initial

10. Setting accept states Right click on any node and select Final

13. Making transitions for nodes After dragging, just specify what transition is being made. Single-clicking on any node will add a reflexive transition Separate multiple input transitions by commas (ex: 0,1)

14. A simple DFA

15. Deleting nodes, transitions Click the skull & crossbones
