 Bigger Bigger Smaller Smaller Reset Reset
Hi all,

I am trying to setup my arduino to switch on an off a light with this relay:

http://dx.com/p/arduino-5v-relay-module-blue-black-121354

I have hooked it up and the LED on the shield blinks when I use my code, But I do not know how to wire my output for my light.

There is a spot for an NC (normally closed) NO(normally open) and a C. I am not sure where I put my positive and negative to wire the whole thing as a circuit.

Any help would be greatly appreciated.

Thanks,

Tayshun

Connect the power source Positive lead to NO, and the C leg to the Positive lead going to your light.
Connect the power source Negative direct to the Negative lead going to your light.
Do not connect anything to NC.
NO will be hot (have power all the time), C will be hot when the relay is commanded on.
NC will never be hot.
