Arduino and heating belt thoughts

Arduino

It was cold today so I bought a heating belt (made in NZ of all places).  I was was looking in to making my arduino UNO in to a temperature controller and found loads of comments about how they can control pumps too.  Pumps?  I looked in to it and found this lovely quote about what they can be used for.

“(transfer) hot wort from the lauter tun to the kettle”

So that’s clear then.
