For the class I am taking, we are to design a circuit with a thermistor in a wheatstone bridge. When the thermistor senses a temperature above 100°F or below 60°F it is supposed to turn on a red LED otherwise a green LED is supposed to be on. The circuit I have turns on the red LED at the 100° set point then turns on the green LED at the 60° set point. I am not sure how to fix that. Any help is greatly appreciated.
Function table (to be edited by OP).
Temperature Green Red
< 60°F Off On
60 - 100°F On Off
> 100°F Off On
