Hi, The example attached shows only 3 lighting circuits, but in the real application we used 13. The idea is when the gates open at the end of the driveway at nightime, lights comes on and off in sequence towards the house. If youre driving away from the house, the lights go towards the gate (so a reverse sequence). Any number of cars can drive in either direction and the lights will follow them in or out. Looks very cool... I hope you can see the file I have attached.
