Reference Language | Libraries | Comparison | Changes
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); |
