Hello,
I got an arduino starter pack recently from oomlout.co.uk. This one: http://www.oomlout.co.uk/arduino-starter-kit-ardx-p-183.html.
It includes a 5v DPTD relay. I understand what it's for and how to use it, but I don't know what to look for when buying more. The range available is all a bit confusing.
I want to control some kit which runs at 12v. I've had a look here but looking at the spec it says the voltage (12, 24 or 48) is the coil voltage, and I guess that means the switching side which I need to be at 5v?
I could do with being told what will suit my needs from here, or at least a link to another shop.
Ideally I'd like someone to either explain the difference between the different types of relay, or point me to somewhere that already exists that explains it.
Thanks!
