Question About Digital Ports

When we are talking digital ports, can Any digital port be used for ANY digital application? For instance if the Roomba on the Tutorial is using D0 and D1 and I am already using those ports, may I use ANY port, say D14,D15 to do the same thing? Or, should i switch the roomba to D0 and D1 and use D14 , D15 for the Other app?




Upgrade to ARC Pro

Your robot can be more than a simple automated machine with the power of ARC Pro!

I'm pretty darn sure you can flip them to whatever digital port you like.

I've had my sonar on D0/D1- D13/14. I've moved my Sabertooth to pretty
much every digital port on the EZ-B.
Roomba can only be on d0
