PNP versus NPN sensors
Disclaimer - I am not an electrical engineer.

It's my understanding that NPN style sensors sink to ground. I.e. - if you plug the signal cable of a NPN into the roborio DIO, it will pull the signal pin to ground and roboRIO will "see" it.

How would you go about hooking up a PNP sensor to the roboRIO?
