Use positive signal to trigger digital input

[tgross35]

Hello everyone,

My electronics team and I are having some trouble figuring this one out: how do you use a positive input to trigger a digital input on the roboRIO? The sensor we intended to use has a positive digital signal. We thought that it might be easier to just control the sensors to an Arduino (which we have it working through currently) then have three possible digital outputs based on calculations the Arduino does, but same problem here. Could anybody help us out with either how to use a positive input or interface an Arduino with the RIO? Thanks,

T
