Wie kan man einen Arduino Sketch mit mit einen taster veränderen?

habe meine frage im Sktech gestellt.

void setup() {
 // put your setup code here, to run once:
pinMode (1,OUTPUT);
pinMode (2,OUTPUT);
pinMode (3,OUTPUT);
pinMode (4,OUTPUT);
pinMode (5,OUTPUT);
pinMode (6,OUTPUT);
pinMode (7,OUTPUT);
}
void loop() {
 // put your main code here, to run repeatedly 
digitalWrite (1,HIGH);
digitalWrite (2,LOW);
digitalWrite (3,LOW);
digitalWrite (4,LOW);
digitalWrite (5,LOW);
digitalWrite (6,LOW);
digitalWrite (7,LOW);
delay (2000);// wen der taster gedrückt ist soll die led auf pin 2 sofort
umspringen soll
digitalWrite (1,LOW);
digitalWrite (2,HIGH);
digitalWrite (3,LOW);
digitalWrite (4,LOW);
digitalWrite (5,LOW);
digitalWrite (6,LOW);
digitalWrite (7,LOW);
delay (2000);
digitalWrite (1,LOW);
digitalWrite (2,LOW);
digitalWrite (3,HIGH);
digitalWrite (4,LOW);
digitalWrite (5,LOW);
digitalWrite (6,LOW);
digitalWrite (7,LOW);
delay (2000);
digitalWrite (1,LOW);
digitalWrite (2,LOW);
digitalWrite (3,LOW);
digitalWrite (4,HIGH);
digitalWrite (5,LOW);
digitalWrite (6,LOW);
digitalWrite (7,LOW);
delay (2000);
digitalWrite (1,LOW);
digitalWrite (2,LOW);
digitalWrite (3,LOW);
digitalWrite (4,LOW);
digitalWrite (5,HIGH);
digitalWrite (6,LOW);
digitalWrite (7,LOW);
delay (2000);
digitalWrite (1,LOW);
digitalWrite (2,LOW);
digitalWrite (3,LOW);
digitalWrite (4,LOW);
digitalWrite (5,LOW);
digitalWrite (6,HIGH);
digitalWrite (7,LOW);
delay (2000);
digitalWrite (1,LOW);
digitalWrite (2,LOW);
digitalWrite (3,LOW);
digitalWrite (4,LOW);
digitalWrite (5,LOW);
digitalWrite (6,LOW);
digitalWrite (7,HIGH);
delay (2000);}
