Man, this thread is golden. I've been looking at doing exactly what you are doing with my tank. I've been looking at getting the arduino duemilanove which is the next step up after the mega. I eventually plan on doing an actual LCD display on mine, with options to edit the dosing schedule via toggles and buttons.
But for now, my main goals are basically, auto top off, water changes, DIY LEd ligthing, along with ph probes, and temp probes.
How long did it take you to familiarize yourself with the necessary components?
I'm a sophomore in Elec. Eng, lots of background in coding, but less so with the hardware.
Looking forward to where this thread goes,
Pianofish, if you're not already familiar with it, try googling Jarduino. Its an Arduino aquarium controller that uses a 3.2" LCD touchscreen. It was made for reef tanks, but its a great starting place and allows you to see what's involved in adding the LCD.
Hunter, I didn't say it before but let me go ahead and say great work on this. This thread will really help a lot of us out, even those already experienced with Arduino. Next logical step, get that thing connected to the web. I found a service called Xively ( www.vively.com
) that allows you to easily track and graph pretty much any data point. Super easy to insert the code, they even provide you with the necessary Arduino sketch, then it tracks anything online. I don't believe you can control anything remotely, but you can have the system send you alerts when it gets to certain conditions (temp too high/low, etc). Really neat service and they do it free.
