Hi, Glen
No, It is only pulsing the led on the screen.
No, It will be in a solid state, High or low depending how you set the setting in Config, Ports & Pins, Output's, (Active Hi or Low).
If it is a 5volt trigger it will. (Most solid state relays are 3 - 30 volts).
M8 turns on flood, M9 turns it off.
Hope this clears the Air(Flood), Chip
