Default Arduino, now what?

Got a really good deal on an Arduino board. Looking to do something brewing related with it. Not looking to go full on automation. Reason I didn't buy a brewtroller or anything. Just looking to fulfill my tinkering needs. Even a digital mash thermometer would make me happy. Any ideas or even proven code?

I'm in the process of building my fermentation temp controller. 3 one-wire sensors and a relay, with room to expand. The coding is not great, as it's my first attempt, but it works, You're welcome to it, though.

There's a lot you can do with those things. If you got the mega, you can do everything the brewtroller can, I believe.

I saw the HABS build some one did a while back. Looks easy enough to do. Got the Arduino for 9 dollars so building it would be cheaper than the brewtroller. Brewtroller > HABS though. If I feel ambitious I may try and tackle that. I do have a brutus 20e so I'm not far from the HABS System.

I guess you already seen it but for other interested. I'm working on something similar similar but gravity, no pumps (yet) .

I also plan to use the arduino as a temp control for my fermentation chamber/keg fridge.

I use an arduino as a temperature controller in my kegerator. It accomplishes the same thing as a love controller, but allows me to set up my own control logic, so I can use the fridge side as a ~60 degree fermentation chamber.

Where did you get the Arduino for 9 dollars?

Ebay. It's the 2009 version but that's all I need to complete the project. The new one is the UNO but that runs about 65. Going to grab a 20x4 LCD. I already have 2 ssrs. I might need to get another or two for the pumps. Unless I can grab the relays from brewtroller for the pumps. Going to be a slow project. I have somewhat of an electronics background as well as programming. My buddy is going to help me out and he programs. Should be a good project. I'll write a step by step when I get it running the way I want it for people that want to do a Brewtroller knock off for possibly quite a bit under the cost.

Cool. I've been away from the forums a while, but come back and people are doing Arduino projects. I just prototyped an e-textile device that would detect tantrum-related behavior in autistic children using an Arduino, accelerometer, and microphone. These projects sound more fun.

It won't hold a candle to the Brewtroller. I'm not after that. I'm just looking to satisify my need to tinker. The code is already out there. I am just going to customize it for my setup. Probably eventually add some valves. I have most of the parts so I think I can do it for a fairly low price. Just going to take some time. I'm always up for learning so even if I can't get it to work correctly, I will still walk away with more knowledge than I came into the project with.

Sounds like you are well versed in the Arduino!

Get some DS1820 one wire sensors and familiarize yourself with the SPI library from the Arduino playground. Your project/code should be very simple after that.
