Arduino/Processing Language Comparison

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.

Arrays

Arduino Processing
int bar[8];
bar[0] = 1; 		int[] bar = new int[8];
bar[0] = 1;
int foo[] = { 0, 1, 2 }; int foo[] = { 0, 1, 2 };
or
int[] foo = { 0, 1, 2 };

Loops

Arduino Processing
int i;
for (i = 0; i < 5; i++) { ... } 		for (int i = 0; i < 5; i++) { ... }

Printing

Arduino Processing
Serial.println("hello world"); println("hello world");
int i = 5;
Serial.println(i); 		int i = 5;
println(i);
int i = 5;
Serial.print("i = ");
Serial.print(i);
Serial.println(); 		int i = 5;
println("i = " + i);
