    We have an existing circuit that is an H-bridge for controlling a thermoelectric cooler. It works and is controlled by software as far as the control algorithm, but this circuit has two resistors that set the heating and cooling current limits. We want to change these fixed resistors to trimpots, so that the heat and cool current limits can be adjusted
