Arduino Powered Aquarium Controller

I thought I would write a few blog posts on an Arduino powered aquarium and aquaponics controller that I have been planning for some time. I have tried to start this project a few times now with various micro controllers, but each time I reach a point where I had some sensors logging to a SD Card and then the project falls over. With my recent desire to learn more about the Arduino community, I figured why not try again but this time document my success (or failure) for the world to see.

To start off, I will take a look at the hardware options, the ones I have chosen and why. Bear in mind, especially if you are new to electronics, that there is no right or wrong way to do things. If you see merit in another way then do it. Make it your own project. You will learn far more than just copying me. If you do go another way, then let me know. I would love to hear why you went a different route and how successful you have been.

Initially I will just be looking at a simple system, looking at water and air temperature as well as the water level in the aquarium. I plan to add more to the system over time, but I wanted to start simple and actually get something working. With that in mind lets dive into the hardware.Continue reading
