I have Arduino Uno R3 and Arduino Ethernet Shield V5.

What's missing in order to control 6+ lights (bulbs) from my home? Those are connected to 220V AC.

My idea is to send a packet via ethernet that has an order for example: "Turn on light 1", "Turn on light 4".

Maybe a relays module?

Obviously the power cables for lights will come from the controller. I want to test now so I can deploy it in real house lights.

Sorry if I am not being too much specific, I am starting to learn.

  • \$\begingroup\$ "power cables for lights will come from the controller" No, the power for the lights will NOT come from the Arduino. The Arduino will send a small signal to a relay that will power the lights. \$\endgroup\$

Yes exactly. $10 or $15 US.
