Thanks alm for your quick reply.
Please forgive me if I am being dense, but I think I still need clarification on this topic and to be sure I am understood I have thrown together a partial circuit (I know this is not a working circuit, I've only included the parts relevant to my question).
Since the thermistor's resistance is proportional (inversely in the case of a NTC) to temperature, would the voltage dropped across R1 decrease as the temperature increases (because the resistance will decrease as the temperature increases) ?
Please explain to me like I'm 5 why my circuit wouldn't work
Thanks for your patience and your help !
