Sorry to sound stupid but what do I connect to each SSR?
I can see the relay has a 5v, ground and 2 connections from the arduino. I presume I need one connection of the arduino to each SSR then the 5v? What about the ground?

Firstly thanks for all the brilliant work with this. I've been looking at BrewPi for a while and collecting the various components but had been hanging out on the shield as it's the most expensive part and I'd enjoy seeing how it all works by putting it together myself.
I'm not sure if...
