I was hoping to use zero hardware and do something in the software but we can always hope, right......

I haven't done a whole lot of testing on it but I do know that the resistance decreases as the temperature gets warmer. Lets say that 1 volt is 100 degrees and .58V is 70 degrees (the thermistor isn't linear). For this application, I will always have to pull it closer to ground. In other words, if the voltage is below .58V, it will read the normal temperature.

I know I can use different combination resistors but then I would have to have about 8 different sized resistors on my board. I will need to try this tomorrow but I wonder if I use resistors in the ones or tens of ohms, instead of the hundreds or thousands of ohms, will that be enough to overcome the thermistor voltage in order to keep the voltage steady. Like I said, the current is low in the circuit, something like a milliamp or so.

For example, instead of using high value resistors ranging from 500ohms to 6000 ohms, I can use a 23ohm and a 3 ohm. I wonder if lower value voltage divider would override the thermistor.
