Arduino Project 005 - LED Chase Lights

RonWang1年前 (2024-06-18)电子编程579

You’re going to use a string of LEDs (10 in total) to make an LED chase effect, similar to that used on the car KITT on Knight Rider or on the face of the Cylons in Battlestar Galactica. This project will introduce the concept of arrays.

// 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

unsigned long changeTime;

 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;}
}
