I need a circuit with a thermistor/temp sensor that will essentially emulate a pot. In other words, I need a voltage divider that varies with the resistance of the thermistor/sensor, but keeps the sum of R1 and R2 constant. (Used to vary duty cycle with 555 timer PWM circuit.
I have a 10k thermistor, a tmp36 (though my supply voltage is 12, so that probably won't work) and an ad592, so if one of those worked it would be great.
