Chasing Light Effect

The project is about to lit up the less in a particular way (in the way u want)

The led's will bright up one by one and then they will travel in a reverse direction.Here, you can use any led you want and also the any colour combination.

Don't forget to like.

The code is as follows.

byte ledPin[]={4, 5, 6, 7, 8, 9, 10, 11, 12, 13};//to define the led's pin

int ledDelay(65);

int direction =1;

int currentLed;

unsigned long changeTime;//this is taken as unsigned because of the function in which it will be used in future

void setup() {

for (int x=0;x<10;x++)

{

pinMode(ledPin[x], OUTPUT);

}

changeTime=millis();

}

void changeLed()

{

for( int x=0;x<10;x++)

{

digitalWrite(ledPin[x], LOW);

}

digitalWrite(ledPin[currentLed], HIGH);

currentLed+=direction;

if (currentLed==9)

{

direction=-1;

}

if (currentLed==0)

{

direction =1;

}

}

void loop() {

// put your main code here, to run repeatedly:

if ((millis()-changeTime)>ledDelay)

{

changeLed();

changeTime=millis();

}

}
