Hi,
For this assignment we were told to build a circuit that uses a thermistor and will generate two digital signals: one of them will be high if the temperature is above 10 C, the other will only be high if it's below 0 C. I believe we are supposed to use an op amp in this as well. I was thinking about finding some way to turn the two signals into one (a wheatstone bridge, maybe?) and then feeding that into 2 comparators, one for each signal. I am not sure how to figure out what the resistances will need to be and I am having trouble just putting the whole thing together. Thanks!
