I've used an Arduino with various sensors. I have been building my own, but may work with commercial sensors if necessary.
I currently have a Uno R3.
I need to control the robot and read sensors from the Arduino via WiFi, since this robot is on wheels.
I think you are right. I may work this out via serial cable and then move to WiFi.
Let me experiment with this awhile. If you don't mind, I'll get back to you when it's time to try wireless.
Thanks
