Reference Language (extended) | Libraries | 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.
| 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 };  | 
| Arduino | Processing | 
|  int i;  for (i = 0; i < 5; i++) { ... }  | for (int i = 0; i < 5; i++) { ... } | 
| 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);  |
