Proyecto arduino simple

Código:

int led = 4;
int led2 = 8;

led3 int = 5;
led4 int = 2; int b = 7;

void setup() {}

pinMode(led,OUTPUT);

pinMode(led2,OUTPUT);

pinMode(led3,OUTPUT);

pinMode(led4,OUTPUT);

pinMode(b,INPUT);

}

void loop() {si ({digitalRead(b)==HIGH)}

digitalWrite(led,HIGH);

Delay(1000); digitalWrite(led2,HIGH);

Delay(1000); digitalWrite(led3,HIGH);

Delay(1000); digitalWrite(led4,HIGH);

Delay(1000); digitalWrite(led,LOW);

Delay(1000); digitalWrite(led2,LOW);

Delay(1000); digitalWrite(led3,LOW);

Delay(1000); digitalWrite(led4,LOW);

Delay(1000); }}
