Got my Futurlec order yesterday, so have a lot of work ahead of me on this project. I'm going to try and post everything here as I progress, and hopefully keep it complete. Wish it wasn't summertime so soon, hours at work are already picking up, and a couple of minor repair jobs (hopefully), that got dump on me after Mother's Day dinner Sunday. Good news though, have a week vacation end of the month, should work out well.
Shouldn't take too long to throw this together once I figure out how to read the sensors. I want to store the min. and max. values on chip, and find what percentage of that range is the current reading. That percentage will be sent out to an LED as its brightness level. The actual numbers, precision, and calibration aren't going to be a concern, since I'm not looking to display them, just RGB levels for Temp, humidity, and pressure. Will probably use an LCD to watch numbers in the beginning, mostly to see that I'm actually getting a reading, and they change throughout the day. Eventually, I'll need to go wireless, and put the sensors outside, or just run a cable for the LED.
