The Arduino language (based on Wiring) is implemented in C/C++, and therefore has some differences from the Processing language, which is based on Java.

(:cellnr:) Serial.println("hello world");

(:cellnr bgcolor=#999999:) int i = 5;
Serial.println(i);

(:cellnr:) int i = 5;
Serial.print("i = ");
Serial.print(i);
Serial.println();

Printing
