Arduino Workshop-LED Chase Effect

Today I will show you how to easily LED Chase Effect this project in just a few steps using Arduino. If you want to complete it, start talking to me. Now we are going to workshop LED Chase Effect We are now going to use a string of LEDs (10 in total) to make an LED chase effect Here are the components we need to complete this workshop

1. 1. Arduino

2. 5mm LED

3. Resistors

Code

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;}
}
