Grafcet (Graphe Fonctionnel de Commande Étape-Transition) is a graphical representation of sequential logic used to design and implement control systems. It is widely used in industrial automation, robotics, and control systems. Grafcet allows users to represent complex sequential logic in a simple and intuitive way.

Action = L (Lights). Starts timer T1 (5s). Transitions to Step 2 when T1 = 5s .
