How should we wire the photoswitchs?

[Mark McLeod]

The digital signal inputs sound good, as well as, the rest of the wiring.
The jumper would have disabled all the digital inputs while it was in place, but they should start working again after it's taken off.
It also sounds like the sensors are working just fine too.

I'd look at the code next.

Which edition of the Framework are you using?
Since there are two that do different things it may just be that you have the one that just drives rather than the one that follows a line.

If you use the Run button on Robot Main.vi in LabVIEW (assuming LabVIEW) you can probe the values coming back from the sensors.
