if we will a relay. what kind of relay are we going to use if we have plenty of bulbs to be used. sorry, i dont know where to start with our project automated residential lighting with online access..
You should ask your instructor who is probably getting a lot of your $$$ to help you with your projects. Relay selection will most likely depend on the voltage and current requirements of the household gizmos you want to control. I posted a link to arduino controllable relays on ebay, read their specifications and compare that to what you need to control.
