    Hi, I was wondering if there are any logic gates that you can buy ready made? After a quick Google I have not been able to find anything that suits, but I may be asking the wrong questions!

    Specifically, all I need is a single AND gate that is able to handle 12v/car voltages. I simply want to illuminate an LED only when two other circuits are active at the same time. Not having worked with electronics much before I realise I am ignorant in this area, but would have thought simply being able to buy a simple "plug and play" unit would be useful for many instances.

    Does such a thing exist? And if so where should I look?

    Thanks.
