Confused with simple output relay
I have a 12v solenoid which when connected to 12v and Neg works perfectly.
So i am introducing a relay (genuine one from FB) to connect it to the FB.
I have the 12v going into COM and i connect the solenoids 12v to NO. If i put it onto NC it engages right away so thats working fine.
However when i start adding in the FB it seems to go wrong. I have the relay hooked up to the 2nd port and the LED comes on very dull when connected. I create just a sample ninja kitty wizard looking at the one output with a button to turn it on and off.
When i run the application and press the button the LED gets brighter on the FB but nothing else happens, the solenoid doesn't change status at all...
Anyone got any ideas what's going wrong?
I am powering the FB from USB if that matters at all? and there is nothing else connected apart from this relay and its the version 4 board.
