Can I control it directly from an Arduino pin?
Yes. The listing says the module can be controlled directly by Arduino and similar microcontrollers, and its listed trigger level of 5-12 V covers a 5 V logic output. Power the relay coils from the module's 12 V supply and connect grounds together.
What is the difference between NC and NO contacts?
NC (normally connected) connects to COM when the relay is off. NO (normally open) connects to COM only when the relay is energized. Use NO for a load that should be on when the channel is triggered, and NC for a load that should be on when the channel is idle.
