Need Help Choosing 110V Relays for Mega 2560

Yes, that would work. It needs a 12V supply for the relays. However, if you look on eBay, you will find lots of inexpensive relay boards, most of which only need 5V.

Thank you for writing back. So would these work?

Again, would I simply choose the pins that I want to use and assign them and connect to the relay board via that 10 pin connector (for the first) or the 6 pin connector (on the second) that I see? Then, put in the 110V wires into the screw terminals?
