Thank you! I appreciate your help.

I can create a curve using my own thermometer but I was hoping to use the B Constant value that i have on the spec sheets. If I set different resister reference voltages and even a different attenuation, to say 11db then i get different voltages and resistance readings. I guess what I can't seem to ...

Ah yes my apologies, I did use a 10k resistor instead of a 150k resistor

I'm using this NTC thermistor: https://www.adafruit.com/product/372 with a B value of 3950. I'm using this diagram: https://1.bp.blogspot.com/-K_9iiN63Csc/V-qxrUYHZpI/AAAAAAAAAOw/CN4YG1Z5oWY8Kf-jPJ1sUaz_railaNoQQCK4B/s320/c1.png which looks like this: https://cdn-learn.adafruit.com/assets/assets/000...
