Sem qualquer erro!
Retirei de um livro, é um programa relativamente simple para fazer uns led's deslizantes.
Código completo:
// Project 5 - LED Chase Effect
byte ledPin[] = {4, 5, 6, 7, 8, 9, 10, 11, 12, 13}; // Create array for LED pins
int ledDelay(65); // delay between changes
int direction = 1;
int currentLED = 0;
unsigned long changeTime;
void setup() {
for (int x=0; x<10; x++) { // set all pins to output
pinMode(ledPin(x), OUTPUT); }
changeTime = millis();
}
void loop() {
if ((millis() - changeTime) > ledDelay) { // if it has been ledDelay ms since
last change
changeLED();
changeTime = millis();
}
void changeLED() {
for (int x=0; x<10; x++) { // turn off all LED's
digitalWrite(ledPin(X), LOW);
}
digitalWrite(ledPin[currentLED], HIGH); // turn on the current LED
currentLED += direction; // increment by the direction value
// change direction if we reach the end
if (currentLED == 9) {direction = -1;}
if (currentLED == 0) {direction = 1;}
}
