First off, I have no experience whatsoever with microcontrollers. I do have considerable experience programming - however not for microcontrollers. However, I do really like to create things - and have possibly set up a target a bit unrealistic for a first project. It would seem simple, but I'm waiting for a little bit of input from some gurus.
Here we go: I would like to use arduino to monitor voltages somewhat specifically. For example, I need to know if a voltage(from an analog input) is approximately +- one of the following voltages: 1.782v, 2.242v, 2.960v, 3.630v, 4.310v, 4.660v, 5.000v. I have read a little about a "limitation"(perhaps not the right word) - arduino can read voltages between 0-5V and something about proportions. I was wondering if having 5v being one of voltages I need to monitor would be a problem as it is the upper limit of arduino? I have heard about voltage dividers and such, but I'm not sure how to implement one or if it is even necessary.
Second, I was wondering if there is a good site for idiots like myself to find material that an idiot can digest quickly. Perhaps one of you friendly people have a site that you use as a quick reference?
