Every Christmas, I set up a train track and town around our Christmas tree. The town has quite a few lights that need to be turned on and off. Recently, I have started trying to make this controlled by c computer and arduino. The only problem is that
I need a relay board to connect the lights to.

There are 11 lights that need to be switched on and off independently, so at least 11 different relays
The voltage on the transformer is 17, so i don't need a normal one for household current

All I need is a relay board to fit those requirements. If you could give me the name of a board and where you found it, it would be much appreciated. If you need any more information, just reply with what you need and I will answer.

Want something like this, make sure the fine details of the card show that it's a 5V coil relay and not 12V.
Seem to be a lot that say 5V, but show 12V relays.

The description says it can be directly controlled, the data presented does not show how that is done.
