First, thanks to all that have posted to this thread, it has helped us greatly. We are still having one problem though. Our code works great on the EDU Bot controller but will not work on our Robot Controller. We have looked at the signals with a scope and think there might be something wrong with our controller(it appears there is something driving the line from the controller). Our question is this! Is there any differences in using the TTL port on the EDU Bot controller and the Robot Controller?
