So I am attempting to send data from the RoboRio to the Arduino. I am using a serial connection, and the arduino is working just fine. But the problem is that I have no idea how to set up the RoboRio side. Should I use the usb port on the rio to connect to the port on the Arduino? Also, how do I code it correctly, it does not seem to work. I am using the Serial class from wpilib, should I use something else? Also, if anyone has a tutorial or trick could they please link me to it, google does not help.
