This is a really basic question but Id like to get my head around it. Im looking at the comparator on the PIC, using a resistor to set the voltage into one side, and then a thermistor on the other side which produces a different voltage to be compared with.
This is the layout of the input resistor:

I dont really understand why you just cant do this:
**broken link removed**
The PIC is connected to 0V. Is it simply done to limit the amount of voltage into the PIC?
