Arduino vs. RoboRIO

The Arduino is a comparably simple micro-controller consisting of one processor core, running one C (C++) program.

The RoboRIO is a somewhat more complex computer that has several CPU cores. It can communicate via the network to the field control system and the drive station, while running a Java (or C++ or LabView) program.

Arduino	RoboRIO
Powered by 7..12V or USB	12 V
USB to program	USB or Network to program
14 Digital or PWM I/O	10 Digital I/O + 10 PWM + 4 Relay outputs
6 Analog Inputs	4 Analog Inputs

Still, they're similar. You can use what you learn to do with one on the other. Their programming languages use the same ideas, albeit in a different dialect.

Arduino (C, C++)	RoboRIO (Java)
setup()	robotInit()
loop()	robotPeriodic() or autonomousPeriodic() or teleopPeriodic()
Serial.println()	System.out.println()
if (..) {...} else {...}	if (..) {...} else {...}
delay(1000)	Thread.sleep(1000)
millis()	System.currentTimeMillis()
pinMode(2, OUTPUT);	DigitalOutput led = new DigitalOutput(2);
digitalWrite(2, HIGH);	led.set(true);
digitalWrite(2, LOW);	led.set(false);
Servo arm; arm.attach(9);	Servo arm = new Servo(9);
arm.write(90);	arm.setAngle(90);
