I'm new to arduino and I think I have all the parts to build the temperature monitor.
Thanks!

the only reason I had it that ways was because I was trying to replicate the functioning of a thermometer and since LM324 responds slowly to temperature changes, I average it over 20 seconds. But yes, you can easily make it to work as a live sensor. I will be posting the code on my website sometime in may, if you want to wait till then.
