I'm new to the Arduino World,
I have been looking at using an Arduino for my project since the beginning of this year, and I think I have decided to run with it.
First off I have seen a few aquarium controllers built with the Arduino, but none of them really hit the spot for me.
The first controller I'm going to build we be run/tested on my inside aquarium, then once its where I want it, it will be implemented on my salt water pond.
I just finished the main housing for this project, and I have it wired in, the power supplied in the unit will be (values not exact), 120VAC - 12VAC - 5VAC - 4VAC - 12VDC - 5VDC - 4VDC...
from my reading I have heard that some probes like a Salinity probe, require AC voltage, but I have not gotten that far yet.
I have a background in Programming, but the 555 Timer is the only IC that I have worked with yet, so the hardware part may take a long time for me to do.
So first things first, I'm not sure what chip to start out with, I've been looking at doing a DIY barebones board, since I will not be using this particular arduino setup for anything else, why not build it into the finished board, right?
now I need to find the right chip, I will be needing a lot of I/O pins (I mean a lot maybe 100-150) I looked into linking arduinos, but everyone says there are ways to get more I/O's without needing another processor. I would also assume I will need a good amount of storage space for the code, I will also need multiple LCD screens and user inputs. I would also like to log data, and have a memory storage for user settings, like a BIOS I guess.
Sorry this is a long post, but its going to be a Long Project for me I think, but I hope not too long.
