The voltage from the FSR varies between 2.5 V and 3.6 V as the FSR resistance varies from 10 k to 26 k. When the voltage is less than 2.5 V, the lower comparator holds the transistor base at ground; when the voltage is greater than 3.6 V, the upper comparator holds the transistor base at ground. In between these values, the 1 k resistor turns on the transistor, turning on the buzzer.

Where can I add a pot to vary the 10K ohm/2.5v value that's input into the TLV1702? Thanks.
