I have no experience when it comes to microcontrollers and have always wanted to get into them and I thought this project might be perfect.

I am making a fish breading tank and the water needs to be chilled to different temperatures depending on where they are in the cycle.
I have the cooling system set up I just need a way to turn a 110v water pump on and off at a specific temperature. I thought the best way to do this was with a microcontroller.

I would like a set up so I could start to make other things with microcontrollers as time goes on.

I am not sure where to go to get started and was hoping to get some help from people who know what theyre doing.

Any input about any of this would be great!

Last time I needed a temperature controller for a liquid bath I bought one of these... Works great. It is "programable" as to temperature and hysteresis...

^^ yep thats the "easiest" ... no need for a micro/programming at all..

Or an easy micro route would be with an arduino/waterproof lm35/relay shield.
