    LM335 to control 555 timer

    Hey, For my project I am trying to use a LM335Z to control the duty cycle of the output of a 555 timer. So the duty cycle output of the 555 timer is 5 to 95% is this possible? I had tried to use a thermistor to control the 555 timer to get a 5 to 95% duty cycle, with a 50% duty cycle at 25...
