This is my first time posting here as I just got an Arduino, and love it!
My question is I have a 5V relay (http://www.shop.fssindustry.com/V23105A5401A201-V23105A5401A201.htm
) but the default on this is without power the relay is closed, so it will pass current. I was wondering if there was a relay like the one that I have, that is the exact opposite, when there is no power the relay will not pass current, only when power is applied to the relay will it allow current to flow.
Thanks for the help!
