I am looking to wire up some relays for the purpose of home automation. I am following this ( http://www.glacialwanderer.com/hobbyrobotics/?p=9) tutorial. I have wired up everything correctly as I can switch the relay on and off with the arduino. When I wire the live (black) wire into the relay, nothing happens. I am not sure what I am doing wrong. I have read the arduino reference materials for relays, but have not really gotten anywhere. The relay that I am using can be found here http://www.allelectronics.com/make-a-store/item/RLY-513/MINI-SPST-3-VDC-RELAY/1.html. The relay is definitely capable of switching AC voltage.
Any help is greatly appreciated.
