I want to connect several components to my arduino project.
4 12v lights, 1 ac appliance. I am thinking that I will use simple relays to connect them to 12v lights and on the COM and NC leads I will connect a seperate 5v supply that will act as an input signal and arduino will know if any of the individual 4 lights are on or off.
I do not have an idea of knowing about the AC appliance because the relay will not work with an AC system.
Any suggestion to improve this method and for the AC appliance is highly appreciated.
