LED bisa dijadikan sebagai indikator dari suatu kondisi. Seperti indikator suhu ( panas atau sejuk), dll
Arduino 1 LED (kedip-kedip)
void setup() {
pinMode(11, OUTPUT);
}
void loop() {
digitalWrite(11, HIGH);
delay(1000);
digitalWrite(11, LOW);
delay(1000);
}
Arduino 3 LED (Traffic Light)
void setup() {
pinMode(11, OUTPUT);
pinMode(7, OUTPUT);
pinMode(3, OUTPUT);
}
void loop() {
digitalWrite(11, HIGH);
digitalWrite(7, LOW);
digitalWrite(3, LOW);
delay(2000);
digitalWrite(11, LOW);
digitalWrite(7, HIGH);
digitalWrite(3, LOW);
delay(500);
digitalWrite(11, LOW);
digitalWrite(7, LOW);
