Pull-up resistor
Pull-down resistor
In-line resistor. Connected between the U1 wiper outputs and
the PICDEM 28-pin header (H3) A/D pins. This is default open
due to the PICDEM Demo Boards may have circuitry on these
pins which would effect the wiper operation. If these are
installed (typically with a 0Ω resistor), ensure that the PICDEM
board has been appropriately modified so that the wiper signal
is not effected.
