int timer = 100; // init Delay
int ledPins[] = {
2, 7, 4, 6, 5, 3
}; // init PIN
int pinCount = 6; //// init jumlah PIN
void setup() {//// init PIN
for (int thisPin = 0; thisPin < pinCount; thisPin++) {
pinMode(ledPins[thisPin], OUTPUT);
}
}
void loop() {
for (int thisPin = 0; thisPin < pinCount; thisPin++) {
digitalWrite(ledPins[thisPin], HIGH);
delay(timer);
digitalWrite(ledPins[thisPin], LOW);
}
for (int thisPin = pinCount - 1; thisPin >= 0; thisPin--) {
digitalWrite(ledPins[thisPin], HIGH);
delay(timer);
digitalWrite(ledPins[thisPin], LOW);
}
}
Artinya dengan array kita bisa membuat loop lampu ....
