A.1 Programmstruktur
Die Grundstruktur eines Arduino-Programms besitzt immer die beiden Funktionen setup() und loop().
Somit sieht der minimale Code für ein Programm (Sketch) so aus:
void setup() // Programmstart{ // Anweisungen}void loop() // Hauptschleife{ // Anweisungen}
Listing A.1: Arduino-Sketch: Grundstruktur
Die Setup-Funktion wird einmalig beim Start des Arduino-Boards oder nach einem Reset ausgeführt. In dieser Funktion werden Grundeinstellungen wie Variablendeklarationen oder Konfiguration der seriellen Schnittstelle vorgenommen. Zusätzlich werden in der Setup-Funktion die Ein- und Ausgänge gesetzt.
