Once the FSR is pressed the output of the comparator should go high. Since there is not really any "delicate" logic behind this schematic I was wondering if a pull-up resistor is really necessary for this application that involves simply turning ON a DC motor while the FSR is pressed. The comparators' data sheet does say that a pull-up is recommended. What do you guys think?
