Hallo ich habe ein Problem mit meinem Code. Er wird immer wieder wiederholt obwohl er erst laufen soll wenn man den button drückt. Könntet ihr mir sagen wo ich in meinem code ein Fehler habe? 
Gruß Yann
int carRed = 12; // LED connected to digital pin 12
int carYellow = 11; // LED connected to digital pin 11
int carGreen = 10; // LED connected to digital pin 10
int pedRed = 9; // LED connected to digital pin 9
int pedGreen = 8; // LED connected to digital pin 8
int button = 2; // Button connected to digital pin 2
int crossTime = 5000;
unsigned long changeTime;
int x;

pinMode(carRed, OUTPUT); // sets the digital pin as output

}
