Re: Wiring Pressure Sensor into Digital Sidecar

The DSC has "pull-up" resistors on all of the GPIOs. This means that, when nothing is connected to them, they will "act" as though they are connected to +5V.

This means you need to hook the pressure sensor up to the GND and SIG pins, such that when the switch closes it will pull the SIG down to 0V.
